In engineering practice, the finite element analysis (FEA) is the most important calculation method for dimensioning components, machines, vehicles and processes. With this simulation tool - as part of the digital twin - the behavior in use can already be examined in the development phase. This shortens development times and enables the evaluation of target variables such as function, material usage and service life. The module deals with the field of structural mechanics using simple examples in theory and practice. Students learn to analyze and evaluate components under static load, to assess the possibilities and limits of the method and to transfer it to new applications.

1. introduction

2. basics of elasticity theory, energy methods

3. basics of FEA using the example of the beam

4. surface and volume elements

5. FEA in practice

6. computer practical course (various application tasks)

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination

• see valid study regulations

Prior knowledge in the following areas is recommended for successful participation in the module: mathematics, mechanics (especially strength of materials), materials engineering, design theory, CAD

Students can describe the basic theoretical relationships of the finite element method. They can explain the essential aspects of modeling. Students will be able to classify the position of FEA in the development process and its contribution to the achievement of objectives in product development.

Students gain a deeper understanding of the mechanical principles and can illustrate their application in FEA. They are able to describe how a simple problem is specifically formulated and calculated. They are able to evaluate the influence of simplifications in modeling on the calculation results. They will be able to critically evaluate the calculation results and derive constructive measures for component improvement.

Students can assess the significance of FEA calculation results in relation to the task, taking into account aspects of good scientific practice and on the basis of their specialist knowledge.

Students can make simple real constructions accessible to calculation with FEA in the course of modeling. They can implement the model in an FEA program, carry out the calculation and evaluate the results.
