An analytical solution of the problem of the pressing of an incompressible elastoviscoplastic material between two rigid coaxial cylindrical surfaces is obtained using the theory of large strains. The velocity of motion of the elastic core, the change in the dimensions of the zones of irreversible deformation and the stresses and strains both in the elastic core and in the flow region are calculated as a function of the variable pressing force.
