Abstract

The destruction of homogeneous obstacles having different physical and mechanical properties is experimentally investigated under interaction with high-strength steel rams. The comparability of the results for different types of obstacles was ensured based on weight equivalency, that is, equality of the weight in the thickness for an area unit of the obstacle. The initial velocity of interaction was varied in the range 50–800 m/s. The double-exposed X-ray pulse recording was used to register ram motion after obstacle penetration. X-ray processing (i) gives the values of ram velocity behind the obstacle depending on its initial impact velocity and (ii) aids analyzing the features of obstacle destruction and their protecting properties by drawing penetration diagrams.
