Abstract: An experimental programme was conducted to investigate the mechanics of perforation of the 7.62-mm NATO Ball round through multiple glass array. Two separate experimental trials were conducted using a multiple glass array as a target. In the first experiments, the spacing in between the glass plates and the areal density were varied. In the second trials, the plates had no spacing in-between and the areal density was fixed. Results indicating the nature of the penetration mechanism are presented with specific reference to the formation of the cone of comminuted glass that propagates from the front plate subsequent to its perforation.
