Summary

The subject deals with the mathematical modeling of forming processes. The aim is to clarify the mathematical background of the finite element method, using practical examples explain the engineering approach to the mathematical modeling. Students are encouraged to apply creatively the skills and knowledge gained at the stage of preparation of the project and at the stage of elaboration and analysis of the result.
