Abstract
In work features of deformation and material fracture with a multilayered covering at high-velocity impact interaction are investigated. The boundary dynamic problem in three-dimensional statement is solved by numerical method of finite elements. The multilayered covering is set in calculations obviously. When modeling of mechanical reaction of a steel substrate, the projectile and a covering intermediate layer made from NiAl ratios of Prandtl-Reuss and the condition equation in the form of Mi-Gruneisen are used. The coat layer from WC-Co shows elastic and fragile behavior. For the description of fracture of materials of a multilayered barrier Hoffman's criterion which includes various strength on tension and compression is used. It is shown that existence of a multilayered covering promotes increase of dynamic strength of a steel basis. It is established that reduction of penetration of the projectile, connected with covering existence, depends on velocity of interaction not linearly.
