Comparison of Resistance to Perforation of Multiple Layers of Thin Steel Sheets with That of a Single Sheet of Equivalent Weight

Abstract

At the request of the Office, Chief of Ordnance, comparative ballistic tests were conducted on five layers of steel .010 in thick, two layers of steel .025 in. thick and a single steel sheet .050 in. thick. All samples were furnished by the American Steel and Wire Company. Because of the size of the samples no significant test was possible with caliber .45 ball ammunition. On the basis of tests with the caliber .22 fragment-simulating projectile, G-2, however, the resistance of a single sheet of thin gauge (.050 in) steel was superior to that of two sheets equivalent in total weight, and the resistance of two sheets of .025 in. steel was superior to that of five sheets of .010 in. steel. Thus no advantage, but rather a disadvantage, is introduced by distributing a given weight among multiple layers.
