Learning Outcomes Knowledge
The student who successfully completes the course will learn the theoretical fundamentals of the finite element method for the analysis of both linear and non-linear behaviour of materials.
Skills
The student who successfully completes the course will be able to consciously use commercial software codes for finite element analysis. Besides, (s)he will be able to write simple software codes to implement the studied algorithms.
Behaviours
The student who successfully completes the course will be able to apply the finite element method to solve material mechanics problems. In particular, (s)he will be able to choose the most appropriate modelling approach, type of elements, level of discretisation, etc., as well as the most suitable solution methods; besides, (s)he will be able to analyse critically the obtained results.
