Abstract
Presented are the results of an experimental investigation of the process of deformation of a body as it impacts and perforates thin plates, the impact speeds being in the range from 3 to 9 km/sec. We show that in a first approximation the radial deformation rate of the body is proportional to the mass velocity determined from the impact parameters; we also show that the initial stage of the process can, with sufficient accuracy, be described within the framework of the simplest hydrodynamic models. We establish the fact that the body debris particles have sizes distributed in accordance with the Rosen-Rammler law and we show that the ratio of the maximum velocity of these particles to the impact velocity is a function of the geometrical dimensions and densities of the body and target.
