Title: Modeling the shock initiation of detonation of heterogeneous explosives

Abstract

In this review the construction of models of the appearance of detonation in heterogeneous explosives and the realization of numerical programs are considered as well as comparison of theoretical and experimental data. Models of explosive breakdown including analysis of the dynamics of pore collapse and models based on formalized kinetics are discussed, mechanisms of hot spot formation are enumerated, and modern experimental methods used to obtain quantitative information are briefly considered, together with Lagrangian analysis of the reacting fluxes. The review illustrates the diversity of existing modeling approaches and macrokinetic equation forms which allow initiation to be described in a one-dimensional formulation and, in some cases, in two-dimensional geometry.
