Intended learning outcomes *
The course will treat both theoretical and more applied FEM modeling aspects. The course also provides the necessary knowledge above the beam theory in structural mechanics. An important goal of the course is to teach students to use a commercial FEM program by analyzing practical problems.
After completing the course the students shall be able to
- explain the basic theory behind the finite element method.
- derive 2D beam element and 4-node plane element.
- describe plate, shell and solid elements.
- use the finite element method to analyse real structures.
- use a commercial FE program.
- explain in which cases a simple dynamic analysis is needed, and the principles behind such analysis.
