An adaptive numerical methodology for mesoscale binder-crystal interactions and damage propagation in impactloaded energetic materials
Abstract
The objective of the proposal is to improve the three-dimensional extrinsic cohesive element formulation explicitly with respect to its ability to represent more accurately the binder-crystal interactions and damage propagation in impact-loaded HE materials. Given the short term (six months) nature of the proposed engagement, the proposed improved methodology is expected to complement the research effort in the field, i.e. contribute to understanding of the behaviour HE material systems, while providing a new platform for implementation of algorithms capable of simulating the thermal effects in the form of localised heating and thus generated hotspots .
