The problem of wedge intrusion in the half-space was considered by R. Hill, E. Lie, and S. Tupper under the Mises yield criterion and Tresca yield criterion. In this case the perfect plastico-rigid body is incompressible. Under the Coulomb–Mohr yield criterion the changing of the material volume in the plasticity area takes place. The intention of this work is researching the strain fields in the different points of plasticity area: on the surfaces of the path velocity discontinuity and in the center of characteristics fan under the plain strain.
