| Abstract |
In the present paper, we study the strain and failure of a two-layer plate each of whose layers is made of a composite material. The layers have mutually perpendicular directions of fiber reinforcement. The plate is impacted by a rigid hammer. The layer composite material is modeled by anisotropic elastoviscoplastic damageable media according to two different (one-velocity and two-velocity) models. We propose to use the two-scale theory of fracture of the composite material. The problem is solved numerically by the method of spatial characteristics. This method permits correctly satisfying the boundary and contact conditions and correctly taking into account the material anisotropy in the difference approximation. We show that the one-velocity model increases the degree of plate fracture compared with the two-velocity model, which takes the stress waves dispersion into account. This can be explained by the fact that the stress field in the unloading wave spreads owing to the microinhomogeneity of the composite layers. |
