Pressing a Rigid Plastic Surface by a Wedge-Shaped Stamp under the Coulomb-Mohr Yield Condition
The problem of treating a surface with a wedge-shaped stamp is considered using the model of an ideal rigid plastic body. The strain fields in the vicinity of singularities of the displacement velocity field (on the discontinuity lines of the displacement velocities and at the center of the fan of characteristics) are investigated taking into account irreversible compressibility.
