Abstract

The effort of developing a constitutive model that explicitly takes into account of the contribution from the interface between energetic crystal and polymeric binder in high explosives is summarized in this report. The starting premise of such a framework is to treat the high explosive as a heterogeneous composite so that each individual constituent can be considered explicitly including the interface. The framework is composed of the following four key components: (1) a representation of the average strain, average stress, and the potential energy of a heterogeneous representative volume element (RVE), (2) a variational principle for specifying the current state of interfacial deformation, (3) a cohesive (or decohesion) law describing the relation between the traction and the displacement jump across the interface, and (4) a micromechanical model for evaluating the potential energy density of the RVE. In this report we summarize the these key ingredients of the framework, while some of the detailed results are listed as references.
