This document summarizes a workshop on lightweight composite design using Altair Engineering software. It discusses ply-based modeling and optimization of composites, including composite free-size optimization to determine efficient ply shapes, size optimization to determine required ply thicknesses, and shuffling optimization to determine a stacking sequence that meets requirements. The goal is to design a minimum mass composite B-pillar under given loads and strains, with the final design achieving a mass of 395 grams while meeting all constraints.
Advanced Design, Analysis and Optimization of Composite StructuresAltair
With stricter requirements on performance and weight, in many cases, composite materials are now becoming the natural choice of designers and engineers given their desirable characteristics such as low weight and high strength. Material properties can be tuned so they are directional – stiffer in one direction while compliant in another for example.

Thermostamping simulation for woven thermoplastic composites (PA) with HyperFormAltair
The thermostamping process of thermoplastic composites can be analyzed with simulation software. In addition to the optimization that can be brought to process (defects, raw material quantity …), the main interest is to integrate results from process into the performance simulation. This article presents an approach to simulate thermostamping of thermoplastic composites (PA) with HyperForm.
The material law is identified from Bias test trials, then, the simulation is performed by HyperForm with the solver Radioss or Ls-Dyna. Fiber orientations (for non-linear anisotropic behavior) and defects (global wrinkles, and wrinkles in the thickness, area with failure risk, thickness variation…) are identified and mapped on structural mesh for mechanical simulation.
Based on this approach, several test/simulation comparisons were performed on both static and dynamic. They demonstrate the necessity of considering the process phase, especially for complex geometries.
Regarding advanced application for such simulation tool: Faurecia Automotive Exterior is developing technologies to produce one-shot visible parts (CFRT thermostamping + overmolding injection in one step). This case study is the most challenging application we are working on. Combining thermostamping simulation and one-shot process brings benefits to both sides thanks to cross results on complex application.
Globaly, to improve the prediction of this simulation tool, next steps are the computation of local density; the consideration of thermal exchanges with the mold during the production process; the modelization improvement of boundary conditions during process (woven holding …, frames…).

RADIOSS, 27 years of past evolution and futureAltair
In the seventies crash simulations in automotive, helicopter & plane industries were done at the concept phase with implicit nonlinear code using beam and spring models. At the same time high speed impacts were solved with finite difference codes with explicit time integration. In the eighties it took several years for the automotive engineers to validate and accept explicit codes to solve car crashes. This was made possible thanks to the power of CRAY vector computers. In the nineties crash became a Computer Aided Engineering (CAE) driven design process in the automotive industry. Simulation driven design process allows design engineers to test many alternatives at a fraction of prototype test cost. Today explicit code is standard for crash simulation and this paper describes the past evolution of the method in the RADIOSS code. In the nineties RADIOSS was successfully applied to stamping and manufacturing processes, implicit time integration was introduced to speed-up quasi static analysis and to performed elastic return or gravity setting using the same code. From the beginning an Arbitrary Lagrange Euler (ALE) integration scheme was built in RADIOSS allowing to solve several Fluid Structure Interaction (FSI) problems. RADIOSS is today a general purpose non-linear finite element code with several applications in automotive, aerospace, defense, nuclear, civil engineering and consumer goods industries.

Topology Optimization Applied to Part Constructed Via FDM (Fused Deposition M...Altair
Unmanned multi-rotors vehicles are a consolidated reality in the modern aeronautical field. These small helicopters consist in a body “hanged” under a set of fixed pitch propellers each powered by an electric motor. These vehicles have great potentials and the research in this topic is increasing aimed at the reduction of the structure weight, therefore maximizing flight endurance, range and payload.
The development of multi-rotor components represents a key challenge both for the structural optimization and the additive manufacturing; they mainly consist in complex shapes where the most important features are robustness and lightness. These parts are usually produced in small series (i.e. eight parts for a single prototype), are subjected to high loads and need to be able to interface different materials.
The work here presented reports the research conducted in cooperation between Politecnico di Torino and Altair Engineering to design and optimize two vital components for the structure of a multi-rotor. These parts represent a challenge because of the main need is to interface the arms, consisting in carbon fiber tubes, with the electric motor flange, on one side, and the body frame on the other, both made in 7075 Alloy. In particular, the second part will also have an important role as structural shock absorber in case of emergency landing.
The use of topology optimization techniques plays a key role to minimize the weight of the components and to improve the productivity of the machines. Moreover, the fused deposition modeling (FDM) technology, applied in this case, allows producing more parts in less time, improving the cost effectiveness of the project.
An important role is played from the Altair tool used for the preliminary design: Inspire. This tool is conceived to quickly and easily generate structural efficient concepts to obtain lighter designs and to eliminate structural design problems, finally providing input files for 3-D printers.

The Team H2politO: vehicles for low consumption competitions using HyperWorks Altair
The Team H2politO is a group of students of the Politecnico di Torino. The student’s background and profiles are very diverse, everyone comes from a different discipline of engineering and together they compose a complete Team. The disciplines range from Automotive and Mechanical to Electronics, Aerospace, Energy, Mathematics, Computer Science, Mechatronics, Management, Cinema and Media and Industrial Design. The Team mission is to shape a new generation of engineers, leaders in their fields, who represent the educational excellence in regard of each of their competencies.
The results of Team passion and hard work are three low-energy consumption vehicles completely designed and made by the Team: IDRA - hydrogen powered prototype; XAM – bioethanol powered parallel hybrid urban concept; XAM 2.0 –EREV city vehicle.
The main goal is to take part and win in Shell Eco-marathon, a competition that every year involves more than one hundreds of students teams arriving from all over Europe. Especially we would like to spread the Shell Eco-marathon values through ours, combining the sustainable development with a vehicle that uses the least possible amount of energy.
H2politO is a different, innovative and somehow unique project, is not just a Team but something more: it is a new type of conceiving educational, professional and personal growth. Team members aim at being perceived as an experimental laboratory where competences, capabilities and potentialities of future’s engineers are fostered. Students strive to become not only solid and advanced technical experts but, equally important, down-to-earth managers having excellent communication, leadership and teamwork skills.
Practical and hands-on experiences are doubtlessly a complementary and enriching form of educational path where it is very important the use of simulation software like HyperWorks. Team members have a real opportunity to lead their educational path by building and crafting their own thesis. Final papers are indeed part of a cluster of thesis which combines all the technological and organizational areas of development H2politO has envisioned and embraced.
The Team believes in hard work as the basis of future success. Students crave for continuously improving and strive for exceeding expectations by nurturing the team spirit in order to create those synergies able to add value to individual performances and capabilities. As a consequence, passion and team-spirit are really the foundation of H2politO values.

AVL software and related services support the entire range of virtual prototyping in the powertrain industry. Altair Engineering is used by a number of major automotive companies as their high-fidelity finite element analysis tool. The highest priority is given to the completion of the workflow for different use cases for strength and durability analysis of engine components as well as NVH analysis of engines and power units. All related simulation tasks are connected by specific interfaces to ensure reduction of overall workflow time and increase in project confidence. The dynamic behavior of engine components (crankshaft, connecting rod, piston, etc.) is simulated using AVL EXCITE as Multi-Body Dynamics (MBD) tool and central software in the workflow. Each component of the crank train and the engine/power unit structure is considered as flexible structure, performing local vibrations as well as global motion. The components are coupled within the MBD tool using various non-linear joints like the elasto-hydrodynamic bearing model. The model setup and meshing is performed with Altair SimLab, which has special plugins fulfilling EXCITE mesh requirements like inserting kinematic couplings at journal/pin center nodes and defining retained nodes at predefined areas. The model reduction is performed with Altair OptiStruct using a very efficient multi-level eigensolver (AMSES). OptiStruct directly generates the flexible body input data (.exb) for AVL EXCITE, whereas the required specification data is just a single command in the input file. After the dynamic simulation in AVL EXCITE the transient results can be passed back to OptiStruct for post processing transient or frequency response analysis. OptiStruct will than calculate motion, stresses and strains whereas results can be passed directly to .h3d or .op2 file format for further fatigue or airborne noise analysis with e.g. EXCITE Acoustics. An overview of the workflows for the use cases strength and durability analysis as well as NVH analysis, together with the integrated FEA tasks and the interaction between the different analysis tasks is given in the presentation.

A sliding door system is used in commercial vehicles and passenger cars to allow a larger unobstructed access to the interior for loading and unloading. The movement of a sliding door on vehicle body is ensured by mechanisms and tracks having special cross-section which is manufactured by rollforming and strech bending process. There are three tracks and three mechanisms which are called upper, central and lower on a sliding door system. There are static requirements as strenght on different directions, rigidity for mechanisms, door drop off, door sag; dynamic requirements as high energy slam opening-closing and durability requirement to validate these products. In addition, there is a kinematic requirement to find out force values from door handle during manuel operating. In this study, finite element analysis and physical test results which are realized for sliding door systems will be shared comparatively.

By the strict discussions regarding energy saving and the goal to reduce CO2, there is a keen demand for light designed automotive structures and the development of electric vehicles. To achieve these goals, a comprehensive method for urban vehicle concepts with electric powertrain and their necessary vehicle structures is presented. The dimensions and packaging of the presented vehicle is based on demands of a future urban vehicle with space for four occupants including baggage, steerable front system wheels and a rear axle including an electric powertrain. In the geometric design phase of the method the vehicle design space is analyzed for global load path with the help of topology optimization (OptiStruct). The load paths are then clustered into different shapes. Concepts for new body in white structures are derived from the results.

Automated Finite Element Model Creation using Structural Condition Data for M...Altair
Advanced structural integrity management software is capable of using a structural Computer Aided Design (CAD) geometry to track the condition of a marine or offshore asset in a virtual environment. ABS Nautical Systems Hull Manager 3D (HM3D) converts a 3D CAD model to a database that stores vessel condition information and provides the ability to track condition changes due to structural degradation. Ultrasonic thickness measurements are mapped directly onto the 3D model such that visualization and utility functions can help determine the remaining life and calculate critical global strength parameters, such as the section modulus and cross sectional areas.
Finite Element Analysis (FEA) based structural reassessments are also facilitated through functionality that allows the auto creation of Finite Element (FE) models in the as-gauged condition and export the models to relevant finite element analysis solvers using the add-on link within HM3D to Altair’s Hyperworks® software. Hyperworks then generates an FE mesh (global or local models, as required by the user) along with the structural properties (metadata), such as the material grades and gauged thickness.
Today, structural engineers face difficulty in practically applying automesh capability to complex or detailed as-built geometry. This is especially true when considering marine and offshore structures, where those assets tend to be very complex geometrically. The challenge posed in this project was to use the as-built structural CAD model as the input and automesh assisted algorithm for creating an FE model along with all the topological metadata, such as material grade and thickness.

FEA Based Design Optimization to Mitigate Anchor Cage Impact Damage RiskAltair
The power of Finite Element Analysis (FEA) simulations can be effectively used for failure analysis and design optimization to improve product reliability and mitigate operational risks. Expandable Liner Hangers used for wellbore construction within the oil and gas industry are complex mechanical systems that require sophisticated setting tools. A key to develop reliable setting tools is to use virtual FEA simulations to predict failure modes and verify system design behavior and performance before making costly prototypes. We can’t afford to do multiple physical prototype tests to validate designs in today’s business economics conditions.
This presentation summarizes FEA based anchor cage impact failure analysis and design optimization of a crush ring to mitigate the impact damage risk for the anchor cage subassembly that is used in an expandable liner hanger setting tool. Altair/Hyperworks and Abaqus/Explicit FEA simulation software are used to perform FEA simulations to optimize the crush ring design. Hypermesh FE mesh morphing capability helped to build various shapes of the crush ring designs quickly without creating CAD models and enabled us to run multiple FEA iterations for faster turnaround. FEA based design optimization helped us to identify design limitations, capture most of the design failure modes and then explore multiple design alternatives for the crush ring design to improve and optimize product performance before building physical (costly) prototypes.

QuickSeeNC first case study 1999
The High Speed Machining (HSM) is the most important technological development in precision engineering. The constant load is a very important factor in HSM. The cutter will break under uneven cutting force. The HSM requires huge tool path to realise the constant load. The milling tool path can easily exceed a half million blocks of machine code. As the feed rate is already very high, it is almost impossible to run test cutting by increasing the feed rate. Visual tool path check is difficult as the tool path overlapping with each other. It takes a long time to run traditional NC simulation software.
Create Radically Better Products with Design Optimization and 3D PrintingDesign World
Designing for additive manufacturing requires a new mindset. Simply designing traditional parts and producing with additive manufacturing will likely result in more costly, slower to produce results. In order to truly benefit from the advantages of the additive process, designers must think differently when designing parts. Topology optimization is a technology that generated ideal structural parts based on loading conditions and the actual intended use of the part.

An engineer working for Northrop Grumman Systems Corporation Marine Systems (NGSC-MS) was given a project to improve their teams’ current NASTRAN results post-processing workflow by writing a script to automate the task. They reached out to Altair for collaboration and Altair engineers were able to quickly determine that Altair’s mathematical modeling environment – “Altair Compose” – would be the ideal solution due to its ability to read, manipulate, and write NASTRAN results. Also, the Open Matrix Language is a scripting language that is familiar to the engineering community. Given sample NASTRAN results and requirements Altair engineers provided a “template” script. The NGSC-MS team was able to quickly understand and modify the script to their goals. The custom results were then viewable in HyperView as a contour plot, which saved a considerable amount of time during post-processing and documentation workflows.
Designing for Sustainability: Altair's Customer StoryAltair
Bush Bohlman was required to perform the structural analysis and timber design for the British Columbia Institute of Technology, (BCIT), student plaza, a pedestrian and public transport user gateway for the institute. The structure needed to establish a strong campus identity with a biophilic design and demonstrable support for sustainable building practices while ensuring structural safety according to local design codes. The hybrid mass timber structure consists of a Cross-Laminated Timber (CLT) canopy, CLT columns, and steel columns. By using S-TIMBER, the engineers were able to simulate the complex two-way bending behavior of the cantilevering roof panels and asymmetrical column layout. Having the model in S-TIMBER allowed for changes to be analyzed and re-designed, without the need to manually design individual timber and steel elements. S-TIMBER's design reports presented the design calculations concisely, yet transparently, for faster and easier reviews.

Lead time reduction in CAE: Automated FEM Description ReportAltair
For each deliverable FE-Model a FEM description report needs to be generated. Since this document contains always the same type of information, it is an ideal candidate to automate the creation of this report. Based on the Hyper Report Tool from Altair, RUAG Space and Altair developed a tool to automatically generate the FEM Description Report. The tool requires the HyperMesh data base and the output files from FEM checks as inputs. Together with the tool template, guidelines are provided on how the data base needs to be set up, such that the report can be created automatically. The main structure of the FEM Description Report is dependent on the assembly structure of the HM data base.
Car makers have to reduce consumption of vehicles and so, are continually looking for solutions to lighten components. For powertrain, components generally mean screwed assembly, contact and fitting interfaces, with different kind of loading to take into account (static and dynamic). Hence, we decided to apply with Altair assistance, a process of topology optimization on an assembly of gearbox housing in order to check its feasibility and efficiency. Several steps had to be solved from exhaustive identification of all mechanical constraints to execution of large models with Optistruct. By the end, the process has been defined and implemented on an existing gearbox and will be soon apply on the next one to design.

Rotating machinery can be found in every industry: automotive, aerospace, energy, etc. The generated vibration environment is typically made of harmonic tones superimposed on background noise. Components mounted on rotating machinery must be designed to survive such mechanical environment over their entire service life. This presentation will concentrate on calculating the fatigue life from sine-on-random excitations using Finite Element Analysis (FEA). It is proposed to derive the statistical rainflow cycle histogram from a sine-on-random spectrum of stress or strain data and then use the appropriate material fatigue curve to obtain the estimated life. This new analysis is complementary to existing features such as SineDwell, SineSweep and (uni- or multi-axes) random PSD. It is part of extensive research work that includes the influence of sigma clipping or the effects of a high kurtosis.

Structural analysis of the Baakenhafen Bridge and the optimisation of chosen ...Altair
The following paper consist of two parts. The aim of the first part is to analyse the problem of thermal loads of steel skew bridges and the displacement caused by them. A 3-spanned steel road bridge named Baakenhafen West is being analysed. In the second part, an optimization of the primary beams of the structure was made. Thus was shown, that there was a possibility to reduce the steel tonnage of the bridge by keeping it safe to use.
