Abstract:

This project focused on 1 the development of a computational capability for analyzing the response of energetic materials such as PBX and GX under dynamic loading and 2 establishment of the ignition behavior of heterogeneous energetic composites as microstructure at the microscale. The thermal-mechanical computational framework CODEX, Cohesive Dynamics for Explosives utilizes a fully dynamic cohesive finite element method CFEM which allows the effects of large deformation, thermomechanical coupling, failure in the form of microcracks, and frictional heating to be tracked. The capabilities resulting from this project can be used to design new energetic materials of interest to the USAF.
