Impact and Ballistic Resistance of a New Aluminium Alloy for Ship Construction Elements

Abstract

The article presents results of examination of the new alloy 7020M intended to be used in shipbuilding. The examination concerned impact properties, verified on a numerical model, and the resistance to perforation (ballistic resistance). Impact and ballistic resistance tests aimed at increasing the operational safety of marine construc-tions to be made of this alloy under the threat of gunfire or explosion.
