Initial boundary-value problems describing the interaction of shock waves with gas-permeable packages of woven metal grids are formulated. Media consisting of two mutually permeating continua - a deformable grid package as the skeleton of the two-phase medium and a pore gas flowing inside the skeleton - are considered. The problem is numerically analyzed using Godunov's scheme with Euler-Lagrange movable difference meshes. The results of experimentally studying the effect of internal plane and cylindrical packages of woven grids on the deformation of the supporting shells of the chambers under internal explosive loading are presented. The numerical results agree with the experimental data.
