We propose a model that allows a single velocity and temperature approximation, and assuming the same pressure for all phases, to calculate the behavior of porous powder mixtures during shockwave loading taking into account the phase transition. Numerical results are compared with available experimental results of different authors to solid and porous media(shock adiabat, double compression shock waves). It is shown that the calculation gives good agreement with experiment for graphite and titanium
