Abstract
A mathematical model of plastic deformation is constructed for initially anisotropic medium. It is assumed that the deformation process for elastic body dictating its own tensors of strain, which continue to act as eigen tensors in the states of plasticity and fracture. In the problem of indentation, the cylinder of a given length with a wedge-like tip is considered as a striker. At a given initial speed of the striker, its maximum penetration depth is determined. The influence of the medium anisotropy and parameters of the striker on the penetration depth is investigated.
