Abstract

Abstract In this Letter, we study the destruction of a duralumin barrier when exposed to an aluminum jet (analogous to a fragment of industrial debris) at a velocity of 7–11 km/s in the presence of copper and aluminum metal shields. The effectiveness fraction of the shield protection, which is determined by the expansion of parts of the destroyed impactor between the shields, is distinguished. An increase in the efficiency of the shield protection due to the phase transitions of the interacting materials of the impactor and shield is determined.
