Abstract
A generalized model of the nonlinear interconnected deformation and fracture of damageable polycrystalline media under high-speed impacts is presented. Geometric nonlinearity, caused by finite strains and the nonlinear and deformation velocity-dependent behavior of materials with anisotropic strengthening and the Bauschinger effect are considered. The proposed model is substantiated, and nonlinear wave processes in a shell of a complex form under impact collision with an obstacle are studied.
