Penetration of the material of particles from a high-velocity flux in collision with a steel obstacle to large depths

Experimental data on the punching of steel obstacles of thickness [asymptotically =]20 mm are given, which show that, in collision and penetration, the particle and obstacle materials go out onto the rear side of the obstacle in the form of thin jets and their interaction with the package of electronic elements is responsible for the degradation of these elements located behind the obstacle.[PUBLICATION ABSTRACT]
