Structural Analysis Programs Applied to Warhead Impact Problems

Abstract

This report is concerned with the application of general purpose finite element structural analysis programs to warhead design work. The capabilities of a number of linear and nonlinear programs including NASTRAN, SAP IV, ADINA, and HONDO are described. These programs are used to solve a number of impact type problems ranging in complexity from a simple one dimensional rod to a conical steel warhead filled with explosive. The results are compared on the basis of accuracy, time and cost, ease of learning, and ease of use.
