Description
Summary:The results of numerical experiments on modeling of shock wave loading of solid and porous carbides with various stochiometric compositions are presented. The model is based on the assumption that all the components of the mixture, including gas, have similar pressure, velocity and temperature. The model has allowed to describe with precision of experiment behavior of porous materials and mixes in a wide range of porosity and pressures. The behavior of complex materials such as carbides is considered as mixture on the basis of these results. The model accurately describes the behavior of the carbides with equal shares of the components of the WC, TiC, TaC, NbC and the behavior of boron carbide B4C. Comparison for data of calculation and experimental data was held for carbides with different porosity.
