Abstract: The damages that form in plane targets made of three steel grades during their shock loading at a rate of 100–650 m/s are statistically processed, and the size distributions of defects are determined. In the general case, the damage accumulation in this strain rate range is shown to be not self-similar. The dynamic fracture toughnesses of the steels are determined, and this characteristic is found to be related to a change in the mechanical properties of the material and the particle velocity range in it on the structural level of the meso II scale.
