Deformation of porous cylindrical bodies under action on their compressing loads

The plastic deformation of cylindrical bodies on a rigid base under the action of a flat stamp is considered. It is assumed that the material of these bodies is porous, the loads are unsteady. Friction forces on the contact surfaces of the ends of the cylinder with the stamp and the base are considered small. After a series of simplifying assumptions, the corresponding mathematical problems are formulated. As a result of an analytical solution, they obtained relations for evaluating parameters characterizing the dynamics of compression of bodies, which at the same time make it possible to evaluate the loads acting on the base material, the degree of compaction of it, as well as the material of deformable bodies.
