Abstract: A model is proposed for calculating the behavior of porous powder mixtures under shock-wave loading in the one-velocity and one-temperature approximations and also under the assumption of identical pressures of all phases. The model takes into account the presence of the gas in pores. The calculated results are compared with available experimental data for solid and porous media (shock adiabats, double compression by shock waves, and adiabatic unloading). The calculated results are in good agreement with the experimental data, including those for two- and three-species (in terms of condensed phases) mixtures.

Keywords: shock adiabat, porous heterogeneous medium, powder mixture, onetemperature approximation, one-velocity approximation, constant Grüneisen coefficient.
