Introduction to HyperWorks for linear static and non linear quasi static anal...Altair
The suite HyperWorks (HW) was introduced in a course of master degree in Mechanical Engineering. The course titled “Design of Production Processes” has the aim to develop a market-pull product in a set of steps beginning with a perception of a market opportunity and ending in production, sale and delivery activities. HW was used for linear static and non linear quasi static analyses to correctly size the different parts which make up the investigated product. The lessons were organized starting from a general overview on Finite Element Analyses, followed by an introduction to HW interface and, finally, the steps necessary to set-up and to analyze the results of different types of simulation were described. Furthermore, topology optimization of particular sub-components were performed by Inspire.

Design by Analysis - A general guideline for pressure vesselAnalyzeForSafety
This presentation file is provided by Mr. Ghanbari and published under permission.
The presentation gives an introduction and general guideline for pressure vessel design by analysis.
The “design by analysis” procedures are intended to guard against eight possible pressure vessel failure modes by performing a detailed stress analysis of the vessel with the sufficient design factors. The failure modes are:
1.excessive elastic deformation, including elastic instability,
2.excessive plastic deformation,
3.brittle fracture,
4.stress rupture/creep deformation (inelastic),
5.plastic instability - incremental collapse,
6.high strain - low cycle fatigue,
7.stress corrosion, and
8.corrosion fatigue
Most of the “design by analysis” procedures that are given in ASME BPVC relate to designs based on “elastic analysis.”
The design-by-analysis requirements are organized based on protection against the failure modes listed below. The component shall be evaluated for each applicable failure mode. If multiple assessment procedures are provided for a failure mode, only one of these procedures must be satisfied to qualify the design of a component.
a)All pressure vessels within the scope of this Division, irrespective of size or pressure, shall be provided with protection against overpressure in accordance with the requirements of this Part.
b)Protection Against Plastic Collapse – these requirements apply to all components where the thickness and configuration of the component is established using design-by-analysis rules.
c)Protection Against Local Failure – these requirements apply to all components where the thickness and configuration of the component is established using design-by-analysis rules. It is not necessary to evaluate the local strain limit criterion if the component design is in accordance with Part 4 (i.e. component wall thickness and weld detail per paragraph 4.2).
d)Protection Against Collapse From Buckling – these requirements apply to all components where the thickness and configuration of the component is established using design-by-analysis rules and the applied loads result in a compressive stress field.
e)Protection Against Failure From Cyclic Loading – these requirements apply to all components where the thickness and configuration of the component is established using design-by-analysis rules and the applied loads are cyclic. In addition, these requirements can also be used to qualify a component for cyclic loading where the thickness and size of the component are established using the design-by-rule requirements of Part 4.
This document provides an overview of Chapter 2 from the textbook "Mechanics of Materials" which covers stress and strain under axial loading. The chapter discusses key topics like normal strain, stress-strain diagrams for ductile and brittle materials, Hooke's law, elastic vs plastic behavior, fatigue, deformations under axial loading, static indeterminacy, thermal stresses, and Poisson's ratio. It also includes sample problems and examples to demonstrate calculating deformations and reactions for axially loaded members.
The document summarizes the key changes and new features in Version 4.40 of the CAESAR II pipe stress analysis software. Some of the main updates include revised piping codes, addition of the B31.11 code, expanded static load case options, automatic generation of hydrotest load cases, updates to the 3D graphics, and addition of new configuration options. The installation process for Version 4.40 is described, which includes running an installation driver from the included CD-ROM.
This document provides design calculations for the seismic and wind loading of an oil storage tank. It calculates the overturning moment due to seismic forces and wind forces acting on the tank. It then calculates the required strength of the tank shell, bottom plate, and anchorage to resist these overturning forces, taking into account the weight and distribution of the tank, contents, roof and supporting structures. Design requirements including allowable stresses and load factors are considered to ensure the structural integrity of the tank under the specified loading conditions.
This document provides an overview of stress analysis and pressure vessels. It discusses key topics including:
- Common pressure vessel shapes like cylinders and spheres and the stresses they experience
- Failure modes from compressive and tensile stresses like buckling and cracking
- Hooke's law and relating stresses and strains for 3D analysis
- Defining and calculating important strains like hoop, longitudinal, and volumetric strains
- Material properties like Young's modulus, Poisson's ratio, bulk and shear moduli
It also provides an ongoing example calculation to illustrate applying the concepts to analyzing stresses and strains in a cylindrical pressure vessel.
The document provides information on the design of pressure vessels. It defines a pressure vessel as a container designed to operate at pressures above 15 Psi. Several factors must be considered in the design, including internal and external pressures, weight, loads, temperature gradients, and stresses. Failure could result from excessive stress, plastic deformation, corrosion, or fatigue if not properly designed. The key components of a pressure vessel include the shell, heads, nozzles, and supports. Common types of heads are torispherical, ellipsoidal, and hemispherical. Formulas are provided to calculate thickness requirements for shells and heads based on internal pressure.
The document provides guidelines for padeye design and calculations for lifting attachments. It states that padeyes shall be designed for at least 5% of the design load applied laterally and that permissible stresses shall follow AISC standards with additional requirements limiting through-thickness stresses to 0.2 times the yield strength if the material does not have through-thickness properties. It then provides examples of calculations for padeye design including shear stress, tension stress, weld shear stress, and dimensional requirements.
This document provides an overview of shear and torsion behavior in reinforced concrete sections. It discusses several key topics:
1. There is no unified theory to describe shear and torsion behavior, which involves many interactions between forces. Current approaches include truss mechanisms, strut-and-tie models, and compression field theories.
2. Shear stresses are produced by shear forces, torsion, and combinations of these. The origin and distribution of shear stresses is explained.
3. Concrete alone cannot resist much shear or torsion due to its low tensile capacity. Reinforcement is needed to resist forces through truss action after cracking.
4. Design procedures from codes like ACI 318 are summarized
This document discusses equilibrium of particles and free body diagrams. It provides an example of drawing a free body diagram for a cylinder suspended by two cables, and using the equations of equilibrium to solve for the unknown tensions in the cables. It also discusses 3D equilibrium, giving an example problem of finding an unknown force on a particle given its position and four other forces.

This document discusses material behavior and properties that are important for structural analysis and design. It defines various types of material stiffness, from material stiffness to cross-section stiffness to member and structure stiffness. It also discusses stress-strain relationships and different material models, including linear elastic, nonlinear elastic, plastic, and viscoelastic models. Finally, it covers key material properties like strength, stiffness, ductility, time-dependent behavior, damping properties, and how these properties depend on the material composition and loading conditions.
This document discusses statically indeterminate structures and thermal stresses. It begins by defining statically indeterminate structures as those where the number of unknowns is greater than the number of equilibrium equations, requiring additional equations. It provides examples of compound bars made of two materials, where the deformations are equal and stresses can be calculated. It also discusses temperature stresses that develop when a material is prevented from expanding or contracting freely due to a temperature change. The temperature strain and stress formulas are provided. Several example problems are then solved to calculate stresses, deformations and loads for statically indeterminate structures and those subjected to temperature changes.
1) Beam shear refers to the tendency of one part of a beam to move vertically relative to an adjacent part. Shear diagrams provide a graphical representation of vertical shear along the length of a beam.
2) Bending moment refers to the tendency of a beam to bend due to applied forces. Moment diagrams show the bending moment along the length of a beam.
3) Examples show how to construct shear and moment diagrams for simple beams under various loadings, and how to determine maximum shear, locations where shear passes through zero, and maximum bending moment.

This document summarizes a study examining how MOOCs can be used to enhance motivation, confidence, and self-regulated learning skills for students from non-traditional backgrounds entering higher education. Survey results found that students have some self-regulatory skills like goal-setting but desire more structure and support.

The study aims to observe students taking a MOOC to better understand how to support self-regulated learning and address tensions between student desires for flexibility versus more regulation and guidance.
This presentation summarizes shear force and its applications in civil and mechanical engineering. It defines shear force as a force acting perpendicular to the substance it acts upon.

This document describes procedures for direct shear testing to determine a material's shear strength. Direct shear testing aims to simulate uniform shear stress across a specimen's cross-section by applying shear forces over small lengths to minimize bending. There are two types of direct shear tests: single shear tests shear across a single surface, while double shear tests shear across two surfaces. The test procedure involves fixing a cylindrical specimen in a shear tool and applying a compressive or tensile load until fracture, then calculating the shear strength from the maximum load and specimen's cross-sectional area.
This document summarizes chapter 6 of the textbook "Mechanics of Materials" which discusses shearing stresses in beams and thin-walled members.
