Abstract

Numerical simulation results of shock wave loading of solid and porous carbides with various stoichiometric compositions are presented. A model for simulation is based on the assumption that all of the mixture components including gas in pores are in thermodynamic equilibrium under shock wave loading. Behavior of condensed phases is described by the Mie-Gruneisen equation of state with Gruneisen parameter being explicitly dependent of temperature. The model accurately predicts behavior of carbides with equal shares of WC, TiC, TaC, NbC components and behavior of boron carbide B 4C while treating the chemical compound as a mechanical mixture. Comparison between experimental and calculated data for carbides of different porosity is presented.
