Multifunctional numerical tool for penetration analysis

Abstract

An advanced analytical/numerical tool for calculating penetration of rigid projectiles into various materials is described. The program is based on cavity expansion theory (CET) and is a further development of an earlier FFI-code to include numerous projectile geometries and target configurations. The new program also contains a graphical user interface making it very simple to define materials and set up penetration simulations. Moreover, it is possible to run multiple simulations to determine the penetration depth as a function of velocity, and the program can also determine ballistic limit and required target thickness to stop a projectile. This report serves as documentation and user manual for the program.
