Abstract
A mathematical model describing the two-dimensional approximation of interrelated processes of nonstationary deformation of packages of metal wire woven meshes and wave processes in the pore gas is presented. The equations are numerically solved using a modified Godunov's scheme. The results of the experimental and computational studies of the shock wave propagation process through a cylindrical package of metal mesh under internal explosive impact are given. The effects of decreasing the intensity of the shock wave after the interaction with the obstacle are evaluated.
