Summary
The subject extends the students abilities to solve the technical problems via
computer modelling. The basic tool is the finite element method and appropriate
application software (Ansys). The subject is focused to these areas of computer
modelling, not covered by other subjects. They are specially : the non-linear
problems - geometric non-linearities, contact problems, the problems of
temperature dilatation, the heat conduction and convection - the steady-state
and the transient analysis, the advanced modelling techniques, the linear
buckling, parametric optimisation.
Learning Outcomes of the Course Unit
1. Identify the problems of mechanics and to define them for FEM solutions.
2. Explain the principles of modelling and simulation by FEM, to describe their algorithms and discuss their advantages and disadvantages.
3. Apply theoretical knowledge to solving practical problems, interpret the results, modify the solution procedure.
4. Analyze and evaluate the results solved by FEM simulation in relation to the used calculation procedures and boundary conditions.
5. Discuss and evaluate the solution procedure and the results obtained by FEM analysis.
