Nonlinear analysis with MSC Nastran
NAS103
Objective
This seminar provides a working knowledge of the nonlinear capabilities of MSC Nastran for static and dynamic analysis. Both
geometric and material nonlinearity are discussed in detail. Nonlinear features of MSC Nastran elements are explained and
several examples are presented. Some practical guidelines for nonlinear analysis are also given.
