Abstract

The problem of normal interaction between a compact steel isotropic cylindrical projectile and an orthotropic plate at the edge of piercing in the range of impact velocity from 50 m/s to 400 m/s. The obstacle is made of an organoplastic material with some initial orientation of its mechanical properties or the same material whose properties are obtained by a 90° rotation of the initial material about the axis OY. The destruction of obstacles is studied and the efficiency of their protective properties is comparatively analyzed depending on the orientation of the elastic and strength properties of the anisotropic material. The problem is solved numerically by the finite element method in the three-dimensional statement. The behavior of the projectile material is described by an elastoplastic model, while the response of the obstacle anisotropic material is described in the framework of the elastic-brittle model with different tensile and compressive strengths.
