Abstract

A dislocation-density based crystalline plasticity, a finite viscoelasticity, and a nonlinear finite-element formulation were used to study the high strain-rate failure of energetic crystalline aggregates. The energetic crystals of RDX (cyclotrimethylene trinitramine) with a polymer binder were subjected to high strain-rate tensile loading, and the predictions indicate that high localized stresses and stress gradients develop due to mismatches along crystalline-crystalline and crystalline-amorphous interfaces. These high-stress interfaces are sites for crack nucleation and propagation, and the predictions are used to show how the cracks nucleate and propagate.
