APPLIED FEM PROJECT | MMT125 |

**Aim**

The FEM (Finite Element Method) is a widely used engineering tool which, for instance, is used during development of products and manufacturing methods. The aim with the course is to give the students knowledge and abilities to work with a commercial FEM-program. The work is carried out on applied problems and includes collection of necessary input values and the interpretation of the received analytical results.

*Knowledge and understanding*

For a passing grade the student must

- from a given problem, be able to create a geometry model for FE-analysis.
- be able to formulate necessary material properties for a FE-model.
- be able to apply loads and boundary conditions on a geometry model for FE-analysis.
- in group, be able to analyse a real problem in order to collect necessary information for FE-modelling and FE-analysis.
- in group, be able to do an evaluation of the achieved results from a FE-analysis.
- in group, be able to document and describe an executed FE-analysis in a technical report in a group, be able to give an oral presentation in order to describe an executed FE-analysis in front of a technically competent audience.

*Skills and abilities*

For a passing grade the student must

- individually be able to work with a commercial FE-program in order to carry out FE-analysis.

**Contents**

The course is focused on the practical use of the __f__inite __e__lement __m__ethod (FEM) and deals only with elementary FEM theory. However central concepts and functions are discussed and explained. The FE-analyses are carried out with a commercial FE-program (ANSYS). Different types of problems such as linear and non-linear static mechanical, thermal, dynamical (frequency/natural vibration) and magnetic flux problems are treated in the practical part of the course. The different types of problems are structured according to geometry, material, loads and boundary conditions in order to be represented in a FE-model. The procedures at and the quality aspects of the FEM calculations are discussed and verifications of the results are made for some analyses. One major project that treats some of the divisions research areas is carried out and reported under the second half of the course. Besides working with FEM the project also gives the possibility to practice other disciplines such as to get into new fields of knowledge and both written and oral presentation.
