Abstract

This paper examines the behavior of a thermomechanical model for energetic materials posed in the companion paper and specifically analyzes three simple motions: (i) constant volume evolution, (ii) one-dimensional, time-dependent longitudinal compression (expansion), and (iii) time-dependent shear. The model describes phase transitions from solid to liquid to gas and exothermic chemical reaction. Thermal and mechanical properties are matched to the explosive HMX in order to illustrate representative dynamics and transitions. Constant volume thermal explosion, shock melting, and shear localization are demonstrated.
