In paper, the influence of anisotropy degree and orientation of strength properties on destruction of materials under impact is investigated numerically and experimentally. The numerical modeling was carried out in three-dimensional statement by a method of finite elements in frameworks of the continual approach of the mechanics of deformable solid. The destruction is described by tensor polynomial criterion of the fourth degree, which takes into account the influence of hydrostatic pressure.
