## Term Project

Every student is required to complete a term project. The objective of this task is that each student obtains hands-on experience in solving analysis problems using a typical finite element code. The term project should address a problem solution in solids and structures, fluid flows or fluid-structure interactions using ADINA.

Some suggested projects:

- Large deformation analysis of a rubber sheet with holes.
- Large deformation analysis of a thick-walled rubber cylinder subjected to internal pressure.
- Large displacement collapse analysis of an elastic thin structure (beam, plate, shell structure).
- Elasto-plastic collapse analysis of a structure, for example a truss bridge.
- Thermal stress analysis of a structure.
- Analysis of fluid flow in a chamber or around an obstruction.
- Analysis of a forced or natural convection fluid flow problem.
- Analysis of a fluid-structure interaction problem.
- Analysis of a problem related to your research.
- Develop a nonlinear finite element program based on STAP. (See textbook)

**Note:** Please choose a (tractable) problem that you can analyze in depth in the very limited time available.

The project work is typically started around the beginning of March and typically involves the following steps:

- Choose a physical problem and consider a "simple" mathematical model of the problem (geometry, loading, material data, boundary conditions) such that in the first instance you can compare your finite element solution results with some analytical results.
- Solve this "simple" mathematical model using ADINA. Obtain an accurate solution by choosing appropriate elements and meshes.
- Next increase the complexity of the mathematical model (for example, assume that the material response is nonlinear) and re-solve. Obtain an accurate solution. Ask "what if" questions and experiment with the finite element method.
- In each case, interpret the calculated response considering the accuracy of the solution of the mathematical model and the adequacy of the mathematical model for the physical problem.

Please hand-in on March 4, 2008 a short description (a few sentences) of the project you would like to select. This description must be approved for you to proceed.
