Fracture mechanics determine the mechanical behaviour, safety and effectiveness of plastic bonded explosives (PBX). Vibrations during production, handling and transport can induce cracks in the explosive particles. In this tool a continuum phase field damage model is used to simulate the propagation of cracks in a HMX particle embedded in sylgard. The solver is based on the MOOSE finite element framework.
