Unsteady compression by a flat stamp of a porous cylindrical body located on a rigid support is considered. It is assumed that slippage occurs on the contact surface of the cylinder end face with the stamp (the friction forces are small), and on the opposite, the friction forces are significant. The compressed body is conventionally divided into two parts: the upper cylindrical and lower conical. In each of these parts, in accordance with the principles of the theory of plasticity, a stress-strain state is evaluated, and, under certain assumptions, the shape and characteristic dimensions of the compressed body are found.
