Course content

The purpose of the subject is to establish methodology for finite element modelling and analyzing structures, with respect to design according to limit state principles, with due account of relevant loads. Topics: Modelling and linear elastic analysis of stiffenered panels and shells as well as global behaviour of ships and platforms. Assessment of error sources the structural analysis, dependent upon the mathematical modelling of loads and structure as well as discretization and round-off errors in the finite element model.
Introduction to nonlinear static and dynamic analysis of structures with geometric nonlinear and elasto-plastic behaviour.

Learning outcome
