Numerical Simulation of Striker Penetration into Anisotropic Elastic and Plastic Obstacles

A method of numerical simulation of dynamical processes of shock and wave interaction and the striker penetration in elastic and plastic anisotropic multilayer obstacles is offered. The problem in axis-symmetrical statement is considered in view of theory of finite deformations in Lagrange variables. For numerical solution, a variant of finite difference method of band adaptive nets is used. Some peculiarities occurring in penetration of strikers into multilayer obstacles are discussed.
