Finite Element Method - Structural Analyses (FSI-ZSY-A)

Academic year 2023/2024
Supervisor: doc. Ing. Pavel Maňas, Ph.D.  
Supervising institute: ÚK all courses guaranted by this institute
Teaching language: English
Aims of the course unit:
Graduates will be able to make basic structural analyses focused on assessment of the stress of components or simple assemblies.
Learning outcomes and competences:
- Ability to make linear and basic nonlinear simulations of stress of components or simple assemblies in the field of mechanical engineering.
- Ability to prepare geometry, prepare mesh, set boundary conditions and basic material properties, assess and interpret results.
- Experience with ANSYS Workbench, and ANSYS Discovery.
- Skills and basic habits necessary for work with FEM systems (software or integrated module in CAD system).
- Understanding of significance of FEM for engineering praxis.
Prerequisites:
- Knowledge of mechanics, dynamics, strength of materials, CAD modelling and material sciences at the level of bachelor's study of mechanical engineering.
Course contents:
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.
Teaching methods and criteria:
Lectures, seminars, self-study.
