The NX Nastran DDAM Analysis (Femap) course offers training in the performance of the Dynamic Design Analysis Method using NX Nastran. DDAM is a U.S. Navy developed analytical procedure for evaluating the design of equipment subject to shock loading. The student will learn to use the NX Nastran DDAM solution (SOL 187) through a presentation of lecture materials and the completion of example problems. The class is focused on NX Nastran and most of the material applies independently of pre- or postprocessor. However, additional material is available for demonstration of use with FEMAP.

WHO SHOULD ATTEND

This course is intended for finite element analysts who need to perform shock analysis per the Navy’s DDAM procedure.
