| Abstract: | The penetration of a steel rod into aluminum alloy plates of various thicknesses is examined. The resistance to penetration
at its initial stages prior to the rod fracture is found to be determined by the dynamic strength of the plate material, its
viscous component (proportional to the plastic strain rate) prevailing at impact velocities of up to 500 m/s. The depth of
penetration varies with the velocity and is conditioned by wave processes in the plate, their scale being dependent on its
thickness.
