Course detail

Finite Element Method - Structural Analyses

FSI-ZSY-AAcad. year: 2021/2022

The course is focused on the analysis of the stress of components or simple assemblies in the field of mechanical engineering. Students get to know essential theoretical fundamentals of finite elements method and the ways how is this method implemented in various categories of software systems.
Particularly is highlighted the difference between various analytical and numerical solutions, interpretation of results of linear and nonlinear modelling, estimation and assessment of various impacts on accuracy of the results. Aim is also placed on methodical making of computational models and interpretation of simulations.
The course integrates knowledge from previous bachelor's study of mechanical engineering and it creates conditions for handling design projects and diploma thesis.
