Resistance of Samples of 'K Panels' to Perforation by Cal. .45 Steel-Jacketed Ball Projectiles and by the Fragment-Simulator, G-2

摘要

The resistance of the samples armor panels to perforation by cal. .45 steel-jacketed ball projectile and by ca. .22 fragment-simulating projectiles, g2, was so appreciably inferior to that of Hadfield manganese steel of equivalent weight that weather cycling tests were considered to be of no interest and were not conducted. It is considered that the theory underlying the fabrication of these samples is not sound from the viewpoint of resistance to perforation.
