Abstract
There exist a few different approaches for the description of shock propagation in porous media. These studies may be divided into three groups; layered models, homogeneous approximation, heterogeneous models. Each of these approaches has its advantages and disadvantages. In the present paper, a new mathematical model is proposed and applied to the problems of piston motion and the rebound of a porous striker from a rigid obstacle. Further, the explanation of the effect of “cold layer” formation by shock compaction of powders, and the separation of powders in the presence of weak shock waves is presented.
