Finite Element Method, AdvancedLaajuus (5 cr)

Objectives

The student will get a deep knowledge in the theoretical basis of the finite element method and is widely able to perform FEM-analyses of structures and machine parts under static loading conditions. The student will learn to perform dynamical and nonlinear analyses, can solve eigenvalues and -modes and analyse the stability of the structure by FEM-program. The student will get conception of the handling of compound structures and large models.
