Interaction of Shock Waves with Materials Having Engineered Microstructures
Abstract
Two computational techniques have been developed to model heterogeneous and non-equilibrium phenomena in reactive inorganic mixtures under high pressure shock wave loading. The first, known by its acronym VIR, is based on a continuum mixture theory and focused on modeling the interaction between chemical reaction and hydrodynamic flow. The second is a new computational tool called DM2 and is based on a discrete element approach. The second is primarily concerned with modeling of complex interactions of thermal, mechanical, and chemical processes at the particle level on the order of micrometers. Significant findings from numerical experiments by use of these techniques include: (1) a demonstration of condensed phase detonation, (2) a mechanistic description of shock-induced chemical reactions at the particle level, (3) a model demonstration of thermal explosion in shear bands, and (4) a confirmation of new deformation and failure response of metals under high-pressure shock compression.
