摘要：

Damage caused by high-strain-rate loading (explosive loading. perforation of target, various impacts) in metallic materials is described briefly. Mechanism of plastic deformation is different at high strain rates in comparison with quasistatic loading because specific phenomena appear. They are stress and shock waves, strain localization (adiabatic shear bands - ASBs), adiabatic heating etc. Generally, it can be said that at high rates of loading no parameter (strain, strain rate, stress, temperature) remains constant. These specific features are illustrated by few examples: perforation of metallic target-by a shaped charge jet, structure of ASBs, and spalling.
