Developments in Constitutive Modeling of Shock-Induced Reactions in Powder Mixtures

Abstract

Shock-induced chemical reactions in inorganic powder mixtures have been the focus of multiple experimental and computational studies due to the possibilities for new material development from high-pressure chemical reactions and the low cost of achieving high dynamic pressures [1–4]. These reactions may additionally benefit from inter-particle mass mixing and rapid thermal changes in the shock wave environment to produce fine microstructures in the product. Reactions of this sort have been shown to take place within about 100 ns (similar to explosive detonations), occur primarily within and just behind the shock front as it propagates through the powder mixture, and lead to nearly complete product formation [5–7].
