Mesoscale Modeling of Energetic Materials

: The goal of the program is to incorporate deformation damage into material models for energetic materials and correlate the damage to changes in energetic behavior. Of primary interest is the effect on the energetic sensitivity of the material from internal damage occurring during a penetration event. Changes in the internal structure due to grain fracture and grain debonding from the matrix material may lead to both a change in the mechanical properties as well as the sensitivity to energetic behavior. This briefing represents interim progress towards these goals.
