`Advanced Engineering Analysis with MSC/PATRAN Advanced FEA-PAT322
Table of Contents
Lesson Title
1. Linear and Nonlinear Analysis of a Cantilever Beam: Understand the concepts and limitations of linear and nonlinear analysis. Perform and compare small and large displacement analyses on a cantilever beam model.
2. Modal Analysis of a Thin Annular Plate: Create a model of a simple supported thin annular plate. Perform a modal analysis to calculate the first 5 natural frequencies and mode shapes. You will then compare these results to theoretical values.
3. Transient Response of a Rocket: Develop a finite element model that represents an axial force (thrust) applied to a rocket over time. Perform a linear transient analysis of the model and compare results to analytic calculations.
4. Multi-Step Analysis of a Cantilever Beam: Demonstrate multi-step analysis set up in MSC/Advanced FEA. Combine large deformation and creep analysis.
5. Gap Elements: Learn the usage of GAP contact elements. Perform non-linear static analysis with various contact conditions.
6. Modeling a Shell to a Solid Elements Transition: Use MPCs to replicate a Solid with a Surface then compare stress results of the Solid and Surface.
7. Element Selection Study: Re-run the cantilever beam you analyzed in Lesson 1 with different Finite Elements. You will study the effectiveness of various 1-D, 2-D and 3-D elements in linear as well as non-linear analysis.
8. Necking of Test Specimen: Understand the importance of the concept of true stress in non-linear analysis by completing this elasto-platic problem.
9. Hertz Contact Problem: Use contact pair approach and multi-step analysis to conduct a non-linear static problem.
10. Crushed Pipe: Model a crushed object by using large displacement analysis and rigid contact analysis.
11. Analysis of a Rubber Seal: A trunk door is analyzed in this exercise. The objective is to examine the stresses and deflections created during the closing of a door by using hyperelastic material properties.
12. Pin Insertion: Resolve nonconvergence issues in to contact analysis then use Tools/Lists as aid to quickly modify element properties associated with contact areas. Use Animation tools to understand the nature of difficulties found in nonlinear static contact analysis.
13a. Linear Bifurcation Buckling Analysis of Thin Plate: A thin plate is modeled under a static load that exceeds the critical load. Run an Advanced FEA bifurcation buckling analysis.
13b. Post-Buckling Analysis of a Thin Plate: Construct a thin plate (with slight imperfection) then place an axial load on the plate. Run an Advanced FEA nonlinear static analysis in order to see the behavior of the plate prior to post-buckling
14. Shock Analysis of a 3-Story Structure: Create a model of a 3-story building using MSC/PATRAN. Perform a response spectrum analysis and compare results to hand solution.
15. Thermal - Structural Exercise: Demonstrate the use of thermal analysis with temperature loading. In addition, demonstrate the use of structural analysis with temperature loading.
16. Transient Heat Transfer Analysis: A 2-Dimensional cross section of a container holding a fluid is modeled in this exercise. Initially, the outside and inside of the container are at 1000°. The temperature of the inner fluid in the model drops from 1000° to 800° in a period of 10 seconds. Perform a transient heat transfer analysis and model convection and conduction.
Appendix
1. Nonlinear Transient Analysisof Vibrating Wire: Develop a 1D model that represents a wire of constant section clamped at both ends, and slowly loaded with a point force at the middle of the wire. Produce two animations of the deformation, one created with quick animation and the other showing true deformation (created using Insight).
2. Sliding Block: This exercise consists of a small block sitting on a baseplate. A pressure is applied to the top of the block, and it is moved 5 units to the right. The purpose of this exercise is to introduce you to setting up a problem involving a Contact boundary condition. In addition, it gives a method for monitoring the progress of a nonlinear analysis.
3. Crushed Pipe II: In this exercise, a symmetrical model of a cylindrical pipe is modeled as being crushed between two rigid bodies. Perform a non-linear static analysis on this model.
4. Thermal - Structural Exercise II: Demonstrate the use of thermal analysis with temperature loading. In addition, demonstrate the use of structural analysis with temperature loading and a temperature field.
5. Analysis of a Rubber Seal II: In this Exercise, you will be increasing the trunk door displacement from exercise 11. The additional deflection will cause the rubber seal to contact itself. Define a general slide line contact condition and perform a non-linear analysis on this model.
6. Analysis of a Rubber Seal II: In this Exercise, you will be increasing the trunk door displacement from exercise 9. The additional deflection will cause the rubber seal to contact itself. Define a general slide line contact condition and perform a non-linear analysis on this model.
