IRJET - An Investigation of Stresses Induced in Curved Beams using MATLAB...IRJET Journal
This document investigates stresses induced in curved beams using MATLAB and finite element analysis (FEA). It analyzes three cross-sectional shapes - trapezoidal, circular, and elliptical - for a crane hook subjected to a 100kN load. MATLAB code is used to calculate stresses in each section, finding the trapezoidal section experiences the lowest maximum stress of 171 MPa. FEA software ANSYS is also used to model each section and determine von Mises stresses, validating the results. The trapezoidal section is identified as optimal for withstanding the load with minimum induced stress.

This paper discusses the design and application of local search methods to a real-life application at a steel cord manufacturing plant. The case study involves a layout problem that can be represented as a Quadratic Assignment Problem (QAP). Due to the nature of the manufacturing process, certain machinery need to be allocated in close proximity to each other. This issue is incorporated into the objective function through assigning high penalty costs to the unfavorable allocations. QAP belongs to one of the most difficult class of combinatorial optimization problems, and is not solvable to optimality as the number of facilities increases. We implement the well-known local search methods, 2-opt, 3-opt and tabu search. We compare the solution performances of the methods to the results obtained from the NEOS server, which provides free access to many optimization solvers on the internet.

One dimensional cutting stock problem 1-d-csp_ a study on data dependent triIAEME Publication
This document discusses a mathematical model for minimizing trim loss in the one-dimensional cutting stock problem (1D-CSP). The model considers order lengths that need to be cut from stock lengths of raw materials. It defines the concepts of first-order and second-order sustainable trims, which represent thresholds for the maximum allowable trim at each cutting stage. Linear approximations are constructed to predict the total trim loss for any set of input data, based on computing trim losses corresponding to the sustainable trim thresholds. The model aims to provide a practical solution for industries like manufacturing transmission towers that deal with 1D-CSP.

The use of Holter Electrocardiograph (Holter ECG) is rapidly spreading. It is a wearableelectrocardiograph that records 24-hour electrocardiograms in a built-in flash memory, making it possibleto detect atrial fibrillation (Atrial Fibrillation, AF) through all-day activities. It is also useful for screeningfor diseases other than atrial fibrillation and for improving health. It is said that more useful informationcan be obtained by combining electrocardiograph with the analysis of physical activity. For that purpose,the Holter electrocardiograph is equipped with heart rate sensor and acceleration sensors. If accelerationdata is analysed, we can estimate activities in daily life, such as getting up, eating, walking, usingtransportation, and sitting. In combination with such activity status, electrocardiographic data can be expected to be more useful.
Stepped or non-prismatic beams are widely used in many engineering applications
and the calculation of their natural frequency is one of the most important problem.
Several methods were used to calculate the natural frequency of stepped beam. In this
work, the Rayleigh methods (Classical and Modified) and finite element method using

Application of Multiple Kernel Support Vector Regression for Weld Bead Geomet...IJECEIAES
Modelling and prediction of weld bead geometry is an important issue in robotic GMAW process. This process is highly non-linear and coupled multivariable system and the relationship between process parameters and weld bead geometry cannot be defined by an explicit mathematical expression. Therefore, application of supervised learning algorithms can be useful for this purpose. Support vector machine is a very successful approach to supervised learning. In this approach, a higher degree of accuracy and generalization capability can be obtained by using the multiple kernel learning framework, which is considered as a great advantage in prediction of weld bead geometry due to the high degree of prediction accuracy required. In this paper, a novel approach for modelling and prediction of the weld bead geometry, based on multiple kernel support vector regression analysis has been proposed, which benefits from a high degree of accuracy and generalization capability. This model can be used for proper selection of welding parameters in order to obtain a desired weld bead geometry in robotic GMAW process.
A nonlinear model for the vibration suppression of a smart composite elastic plate using graphical representation involving fuzzy control is presented. The plate follows the von Kármán and Kirchhoff plate bending theories and the oscillations are caused by external transversal loading forces, which are applied directly on it. Two different control forces, one continuous and one located at discrete points, are considered. The mechanical model is spatially discretized by using the time spectral Galerkin and collocation methods. The aim is to suppress vibrations through a simulation process within a modern graphical computing environment. Here we use MATLAB/SIMULINK, while other similar packages can be used as well. The nonlinear controller is designed, based on an application of a Mamdani-type fuzzy inference system. A computational algorithm, proposed and tested here is not only effective but robust as well. Furthermore, all elements of the study can be replaced or extended, due to the flexibility of the used SIMULINK environment.

TOWARDS A UNIFIED IN-PROCESS GEOMETRIC MODEL FOR MULTIPLE MACHINING AND Layer...Liu PeiLing
There are many fabrication processes in modern manufacturing, but current modeling and simulation tools only simulate a few unit processes based on different geometry models. To overcome the data exchange problem between different models, this paper studies various in-process geometry models together with their working systems / prototypes for traditional manufacturing processes. Novel hybrid multiple-machining and layered manufacturing processes are presented to identify critical issues. Working towards a vision of pervasive modeling and simulation, a unified Voxel-based in-process geometry model for multiple-machining and layered manufacturing simulations is proposed and discussed.
Since the skeleton represents the topology structure of the query sketch and 2D views of 3D model, this paper proposes a novel sketch-based 3D model retrieval algorithm which utilizes skeleton characteristics as the features to describe the object shape. Firstly, we propose advanced skeleton strength map (ASSM) algorithm to create the skeleton which computes the skeleton strength map by isotropic diffusion on the gradient vector field, selects critical points from the skeleton strength map and connects them by Kruskal's algorithm. Then, we propose histogram feature comparison algorithm which adopts the radii of the disks at skeleton points and the lengths of skeleton branches to extract the histogram feature, and compare the similarity between two skeletons using the histogram feature matrix of skeleton endpoints. Experiment results demonstrate that our approach which combines these two algorithms significantly outperforms several leading sketch-based retrieval approaches.
This document presents an intelligent feature recognition methodology (IFRM) to develop a feature recognition system for prismatic parts using feature-based modeling systems as input. The IFRM consists of three main phases: 1) converting CAD data in IGES/B-rep format into an object-oriented data structure, 2) classifying extracted features from the data file into different groups, and 3) mapping the extracted features for computer-aided process planning. The methodology aims to achieve integration between CAD and CAM by developing a feature recognition algorithm that can communicate with different CAD/CAM systems. Algorithms are presented to extract features from 2.5D prismatic parts using feature-based modeling system input through geometry analysis and feature classification.
For the processing of data such as with 3D printing, Virtual Reality (VR) and
Augmented Reality (AR), there is a need to seek technology which accurately and quickly analyzes the
three-dimensional structures including that of complicated 3D forms. However, unlike in 2D situations
when there are few data points, there is not yet an established method for processing it quickly for 3D
forms due to the fact the objects constructing it are complicated as well as the fact that there is a lot of
data points within the space. Generally, when illustrating a complicated form, a method is used
whereby an object with the complicated form is generated using several primitive shapes. This method
is used in various 3D modelling software because the position of the object can be intuitively and
freely changed and since it can be easily written within DirectX or Java 3D, OpenGL, etc. In this
thesis, it was shown that by using GPGPU (General-Purpose computing on Graphics Processing
Units) in respect of an algorithm with a solid angle, the inside-outside judgement could be conducted
quickly. Specifically, a measurement of inside-outside judgement processing was made for
complicated shapes created from several primitive shapes as well as the measurement of processing
time of several primitive shapes.
This document presents a dual transform method for medical image compression that uses both singular value decomposition (SVD) and Haar wavelet transform. It compares the proposed dual transform method to existing Haar wavelet-SPIHT and DCT-SPIHT compression methods on 3 medical images. The dual transform method achieved higher compression ratios and PSNR values at 0.4 bits per pixel compared to the other methods, indicating better preservation of image quality at higher compression. The dual transform is thus concluded to be suitable for compressing medical images where no deterioration of image quality is acceptable.

Model Development and Analysis of Four Bar Mechanismijsrd.com
Abstract Mathematical modeling / Simulation is a process of designing a model of a real system and conducting experiments with it for the purpose of understanding the behavior of the system. It is widely used for analyzing mechanisms also. Investigations of the various stages of mechanism design like synthesis and analysis using mathematical model is an effective tool by high development of computing technique, which enables complicated problems to be solved with minimum number of assumptions. Four bar mechanisms are widely used in automobiles and industrial applications. The present work aims at developing a computational environment for synthesizing and analyzing the mechanism both kinematically and kinetically. This work presents a simple and good mathematical model for getting the relevant parameters like link lengths, their velocities, their accelerations and the forces acting on it with the input of output function. The computational environment for the model is developed using a ‘Ch’ language, an embeddable C/C++ interpreter. The effect of varying parameters like link lengths, output functions on displacement, velocity, acceleration and forces has been studied.
This document describes a method for interactively manipulating parametric 3D shapes through direct brush strokes on the shape itself, rather than through adjusting individual hyper-parameters. The method works by amending the underlying direct acyclic graph (DAG) of the parametric shape to enable local differentiation of the shape with respect to its hyper-parameters. This allows the user's brush strokes to be interpreted as changes to the hyper-parameters through inverse control, without requiring any additional setup by the shape designer. The method is automatic, flexible, and non-invasive to existing parametric shape engines.
IRJET- 5th Order Shear Deformation Theory for Fixed Deep BeamIRJET Journal
This document presents a study on the flexural response of fixed deep beams using a 5th order shear deformation theory. The theory accounts for shear deformation effects through the use of a 5th order function in the thickness coordinate. Equilibrium equations are derived using the principle of virtual work. Stress analysis is carried out for deep beams under varying loads and results are compared to other theories. It is found that the 5th order theory provides stress distributions through the thickness that are in excellent agreement with other refined shear deformation theories, and satisfies boundary conditions of zero shear stress at beam surfaces.

Solid manipulation involves evaluating and modifying 3D solids. It includes displaying solids as wireframes or shaded images, evaluating points and intersections on solids, trimming solids using boundary surfaces, splitting solids into sub-solids through segmentation, applying transformations like translation and rotation, and editing solids by changing their geometry or topology using their CSG trees. The document then describes each of these solid manipulation techniques in more detail.
SURVEY ON POLYGONAL APPROXIMATION TECHNIQUES FOR DIGITAL PLANAR CURVESZac Darcy
This document summarizes and compares three techniques for polygonal approximation of digital planar curves:
1) Masood's technique which iteratively deletes redundant points and uses a stabilization process to optimize point locations.
2) Carmona's technique which suppresses redundant points using a breakpoint suppression algorithm and threshold.
3) Tanvir's adaptive optimization algorithm which focuses on high curvature points and applies an optimization procedure.
The techniques are evaluated on standard shapes using measures like number of points, compression ratio, error, and weighted error. Masood's technique generally had lower error while Tanvir's often achieved the highest compression.
An iterative morphological decomposition algorithm for reduction of skeleton ...ijcsit
Shape representation is an important aspect in image processing and computer vision. There are several skeleton transforms that lead to morphological shape representation algorithm. One of the main problems with these algorithms is in selecting the skeleton points that represent the shape component. If the numbers of skeleton subsets are reduced then the reconstruction process will be easy and time consuming. The present paper proposes a skeleton scheme that selects skeleton points based on the largest shape element. By this, overall skeleton subsets will be reduced. The present method is applied on various images and is compared with generalized skeleton transform and octagon-generating decomposition algorithm.

In stereo vision, the epipolar geometry is the intrinsic projective geometry between the two views. The
essential and fundamental matrices relate corresponding points in stereo images. The essential matrix
describes the geometry when the used cameras are calibrated, and the fundamental matrix expresses the
geometry when the cameras are uncalibrated. Since the nineties, researchers devoted a lot of effort to
estimate the fundamental matrix. Although it is a landmark of computer vision, in the current work, three
derivations of the essential and fundamental matrices have been revised. The Longuet-Higgins' derivation
of the essential matrix where he draws a mapping between the position vectors of a 3D point; however, the
one-to-one feature of that mapping is lost when he changed it to a relation between the image points. In the
two other derivations, we demonstrate that the authors established a mapping between the image points
through the misuse of mathematics.
Pick and place task is one among the most important tasks in industrial field handled by “Selective
Compliance Assembly Robot Arm” (SCARA). Repeatability with high-speed movement in horizontal plane is
remarkable feature of this type of manipulator. The challenge of design SCARA is the difficulty of achieving
stability of high-speed movement with long length of links. Shorter links arm can move more stable. This
condition made the links should be considered restrict then followed by restriction of operation area
(workspace). In this research, authors demonstrated on expanding SCARA robot’s workspace in horizontal area
via linear sliding actuator that embedded to base link of the robot arm. With one additional prismatic joint the
previous robot manipulator with 3 degree of freedom (3-DOF), 2 revolute joints and 1 prismatic joint is become
4-DOF PRRP manipulator. This designation increased workspace of robot from 0.5698m2 performed by the
previous arm (without linear actuator) to 1.1281m2 by the propose arm (with linear actuator). The increasing
rate was about 97.97% of workspace with the same links length. The result of experimentation also indicated
that the operation time spent to reach object position was also reduced.

It simulates the tool and workpiece movements to calculate cutting forces and surface topography at each step of the milling process in 3D.
IRJET- Static Analysis of Cutting Tool using Finite Element ApproachIRJET Journal
This document summarizes a study that used finite element analysis to examine the static stress on a single point cutting tool under different tool geometry parameters. A CAD model of the cutting tool and workpiece was created in ANSYS. The tool's total deformation and von Mises stress were calculated for variations in relief angle, back rake angle, and chip formation. The results showed that increasing the relief angle and back rake angle decreased tool stress levels significantly. A positive back rake angle helped move chips away from the workpiece and led to easier material shearing over compression. Continuous chip formation with a positive rake angle also helped maintain tool safety during hard material cutting. In conclusion, a positive rake angle is preferred for machining
Designing of 3D Printer Based on Polar Coordinate SystemIRJET Journal
This document describes the design of a 3D printer that uses a polar coordinate system to control axis movement. Some key points:
- The printer uses polar coordinates (r, θ, φ) rather than Cartesian coordinates (x,y,z) to potentially reduce the number of parts needed in the machine and make it more compact.
- It has three main axes of movement - the theta axis controls rotation of the print bed, the radius axis controls the distance of the print head from the center, and the z-axis controls print head height.
- The design was created using CAD software and the axes will be controlled by G-code from the CAD model.
- Using polar coordinates allows converting

The computational environment for the model is developed using a ‘Ch’ language, an embeddable C/C++ interpreter. The effect of varying parameters like link lengths, output functions on displacement, velocity, acceleration and forces has been studied.
This document describes a method for interactively manipulating parametric 3D shapes through direct brush strokes on the shape itself, rather than through adjusting individual hyper-parameters. The method works by amending the underlying direct acyclic graph (DAG) of the parametric shape to enable local differentiation of the shape with respect to its hyper-parameters. This allows the user's brush strokes to be interpreted as changes to the hyper-parameters through inverse control, without requiring any additional setup by the shape designer. The method is automatic, flexible, and non-invasive to existing parametric shape engines.
IRJET- 5th Order Shear Deformation Theory for Fixed Deep BeamIRJET Journal
This document presents a study on the flexural response of fixed deep beams using a 5th order shear deformation theory. The theory accounts for shear deformation effects through the use of a 5th order function in the thickness coordinate. Equilibrium equations are derived using the principle of virtual work. Stress analysis is carried out for deep beams under varying loads and results are compared to other theories. It is found that the 5th order theory provides stress distributions through the thickness that are in excellent agreement with other refined shear deformation theories, and satisfies boundary conditions of zero shear stress at beam surfaces.
presentation on solid manipulation in computer aided designRakshit vadi
Solid manipulation involves evaluating and modifying 3D solids. It includes displaying solids as wireframes or shaded images, evaluating points and intersections on solids, trimming solids using boundary surfaces, splitting solids into sub-solids through segmentation, applying transformations like translation and rotation, and editing solids by changing their geometry or topology using their CSG trees. The document then describes each of these solid manipulation techniques in more detail.
SURVEY ON POLYGONAL APPROXIMATION TECHNIQUES FOR DIGITAL PLANAR CURVESZac Darcy
This document summarizes and compares three techniques for polygonal approximation of digital planar curves:
1) Masood's technique which iteratively deletes redundant points and uses a stabilization process to optimize point locations.
2) Carmona's technique which suppresses redundant points using a breakpoint suppression algorithm and threshold.
3) Tanvir's adaptive optimization algorithm which focuses on high curvature points and applies an optimization procedure.
The techniques are evaluated on standard shapes using measures like number of points, compression ratio, error, and weighted error. Masood's technique generally had lower error while Tanvir's often achieved the highest compression.
An iterative morphological decomposition algorithm for reduction of skeleton ...ijcsit
Shape representation is an important aspect in image processing and computer vision. There are several skeleton transforms that lead to morphological shape representation algorithm. One of the main problems with these algorithms is in selecting the skeleton points that represent the shape component. If the numbers of skeleton subsets are reduced then the reconstruction process will be easy and time consuming. The present paper proposes a skeleton scheme that selects skeleton points based on the largest shape element. By this, overall skeleton subsets will be reduced. The present method is applied on various images and is compared with generalized skeleton transform and octagon-generating decomposition algorithm.

In stereo vision, the epipolar geometry is the intrinsic projective geometry between the two views. The
essential and fundamental matrices relate corresponding points in stereo images. The essential matrix
describes the geometry when the used cameras are calibrated, and the fundamental matrix expresses the
geometry when the cameras are uncalibrated. Since the nineties, researchers devoted a lot of effort to
estimate the fundamental matrix. Although it is a landmark of computer vision, in the current work, three
derivations of the essential and fundamental matrices have been revised. The Longuet-Higgins' derivation
of the essential matrix where he draws a mapping between the position vectors of a 3D point; however, the
one-to-one feature of that mapping is lost when he changed it to a relation between the image points. In the
two other derivations, we demonstrate that the authors established a mapping between the image points
through the misuse of mathematics.
Pick and place task is one among the most important tasks in industrial field handled by “Selective
Compliance Assembly Robot Arm” (SCARA). Repeatability with high-speed movement in horizontal plane is
remarkable feature of this type of manipulator. The challenge of design SCARA is the difficulty of achieving
stability of high-speed movement with long length of links. Shorter links arm can move more stable. This
condition made the links should be considered restrict then followed by restriction of operation area
(workspace). In this research, authors demonstrated on expanding SCARA robot’s workspace in horizontal area
via linear sliding actuator that embedded to base link of the robot arm. With one additional prismatic joint the
previous robot manipulator with 3 degree of freedom (3-DOF), 2 revolute joints and 1 prismatic joint is become
4-DOF PRRP manipulator. This designation increased workspace of robot from 0.5698m2 performed by the
previous arm (without linear actuator) to 1.1281m2 by the propose arm (with linear actuator). The increasing
rate was about 97.97% of workspace with the same links length. The result of experimentation also indicated
that the operation time spent to reach object position was also reduced.
This document presents a novel simulation model for face milling that has been developed and embedded in a CAD environment. The model simulates tool kinematics precisely and considers the effect of cutting geometry on surface roughness. The accuracy of the simulation model was verified through experiments. The model can determine optimal cutting conditions for face milling and can be integrated into CAD/CAM systems. It simulates the tool and workpiece movements to calculate cutting forces and surface topography at each step of the milling process in 3D.
IRJET- Static Analysis of Cutting Tool using Finite Element ApproachIRJET Journal
This document summarizes a study that used finite element analysis to examine the static stress on a single point cutting tool under different tool geometry parameters. A CAD model of the cutting tool and workpiece was created in ANSYS. The tool's total deformation and von Mises stress were calculated for variations in relief angle, back rake angle, and chip formation. The results showed that increasing the relief angle and back rake angle decreased tool stress levels significantly. A positive back rake angle helped move chips away from the workpiece and led to easier material shearing over compression. Continuous chip formation with a positive rake angle also helped maintain tool safety during hard material cutting. In conclusion, a positive rake angle is preferred for machining
Designing of 3D Printer Based on Polar Coordinate SystemIRJET Journal
This document describes the design of a 3D printer that uses a polar coordinate system to control axis movement. Some key points:
- The printer uses polar coordinates (r, θ, φ) rather than Cartesian coordinates (x,y,z) to potentially reduce the number of parts needed in the machine and make it more compact.
- It has three main axes of movement - the theta axis controls rotation of the print bed, the radius axis controls the distance of the print head from the center, and the z-axis controls print head height.
- The design was created using CAD software and the axes will be controlled by G-code from the CAD model.
- Using polar coordinates allows converting

This document describes new algorithms for simulating etching in the fabrication of 3D microelectromechanical systems (MEMS) and MEMS-tunable lasers. The algorithms improve on existing 2D methods by applying boundary smoothing and remeshing after subtraction operations. They also use domain decomposition to more efficiently simulate etching of complex 3D structures by decomposing the structure into blocks. Numerical results demonstrating the algorithms' performance on realistic 3D MEMS and laser devices are presented and analyzed.

The document discusses research on integrating geometric and mechanistic models for cutting process simulation and feedrate optimization in five-axis milling of free-form surfaces. It presents a method for extracting cutter-workpiece engagement geometry from CAD/CAM toolpaths to be used as input for a discrete mechanistic force prediction model. Experimental validation showed good agreement between simulated and measured cutting forces. The integrated modeling approach uses geometric simulation to dynamically update the workpiece model and determine cutter contact areas, while the mechanistic model estimates forces to calculate optimal feedrates within constraints of part quality, tool life, and machine limitations.

This document presents a new analytical method for identifying stability lobes in high-speed machining of thin ribs. It describes developing a stability lobe diagram that shows the relationship between axial depth of cut and spindle speed, with lobe number as a parameter. The method involves using experimental modal analysis to determine dynamic characteristics of the machine-tool system and then using mathematical equations to simulate the real and imaginary parts of the frequency response function. This allows predicting stable and unstable machining regions. The document outlines the specific steps of the proposed method and shows examples of simulating the frequency response function and stability lobes using Mathcad software. It concludes that the method can predict stability lobes considering workpiece flexibility and that future work will incorporate experimental validation.
This document summarizes a study that used response surface methodology and grey-Taguchi technique to model and optimize the wire electrical discharge machining (WEDM) process. Experiments were conducted varying 6 process parameters (discharge current, pulse duration, etc.) at 3 levels. Models were developed relating the responses of material removal rate, surface finish, and kerf to the parameters. Predicted data from the models were used in a Taguchi design to find the optimal parameter combination for maximizing material removal rate and surface finish while minimizing kerf.

Advanced Algorithms for Etching Simulation of 3d Mems-Tunable Lasers ijctcm
This The integrated circuits (ICs) industry uses a number of technology computer aided design (TCAD) software tools to simulate the manufacturing and the operation of many ICs at different levels. At very low level, the simulation tools are used to simulate the device fabrication and design. These simulation tools are based on solving mathematical equations that describe the physics of dopant diffusion, silicon oxidation, etching, deposition, lithography, implantation, and metallization. The simulation of physical etching solves etching equations to calculate the etching rate. And this rate is used to move the geometry of the device. The simulation of non-physical (geometrical) etching is based on geometrical Boolean operations. In this paper, we are proposing new and advanced geometrical etching algorithms for the process simulation of three dimensional (3D) micro electro mechanical systems (MEMS) and MEMStunable vertical cavity semiconductor optical amplifiers (VCSOAs). These algorithms are based on advanced domain decomposition methods, Delaunay meshing algorithms, and surface re-meshing and smoothing techniques. These algorithms are simple, robust, and significantly reduce the overall run time of the process simulation of 3D MEMS and MEMS-tunable laser devices. The description of the proposed etching algorithms will be presented. Numerical simulation results showing the performances of these algorithms will be given and analyzed for realistic 3D MEMS and MEMS-tunable laser devices.

Smart Prediction Of Surface Finishing Quality Of En-8 Work Piece By Ann ModelIJERA Editor
Turning is a material removal process a subtractive form of machining which is used to create parts of circular
or rotational form of desired geometry/shape by removing unwanted material. Accuracy of any process depends
on involvement of operational variables. The operating parameters that contribute to turning process are Cutting
speed, Depth of cut, Feed rate. Vibrations, tool life, tool wear, surface finish and cutting forces etc are also in
direct relation with values selected for process parameters. So to improve the efficiency of process and quality
of the product it is necessary to control the process parameters. We have considered surface roughness the
parameters with main focus as it dictates the aesthetics and sometimes ergonomical characteristics of the
product. In this work a neural network is created using feed forward back propagation technique for simulation
of the process using the Matlab Neural network toolbox. So with assurance of accuracy of the predictive
capabilities of the neural network it was then used for optimization.

The curved shape of strip is obtained by pulling it into the transverse direction using the lead weights or pegs.
Offset effect on the S-Bend structure losses and optimization of its size for...IJECEIAES
The S-Bend structures are heavily exploited to join optical components. Reducing the power loss caused by the curve is the main objective in the design step of these components. However integrated optical circuits require S-Bend waveguide to be low loss and compact sized. In this paper, we present a contribution to link the curved structure to the straight waveguide by using the simulated bend function available in the Beam propagation tool of the Rsoft commercial software package. Simulation results confirm that this approach allows a reduction of the size of the curved structure with offset with relatively minimum of losses for photonic field.
