4K440 - Nonlinear finite element method for solids

Contents

Nonlinear finite element analysis is nowadays an essential component of computer-aided design. Experimental testing of prototypes is increasingly being replaced by nonlinear finite element simulations (so-called virtual prototyping) because this provides a more rapid and less expensive way to evaluate design concepts. In most companies nonlinear finite element software packages are used as a simulation black box. However, a nonlinear finite element analysis confronts an engineer with many choices and pitfalls. Selections made in the model formulation, mesh discretizations, element types, the solution procedure etc. may have a tremendous effect on the final results. Therefore, an engineer must be aware of these influences in order to provide an adequate interpretation of the results.

Learning objectives

To understand and to gain insight into the fundamental concepts and methods of a non-linear finite element analysis for solids, which are necessary to be able to create an adequate finite element model for a non-linear engineering problem and to interpret the numerical results accordingly.
