Fragmentation of Shallow - Grooved Warhead No. 142

Abstract

This test was conducted to determine the ability of shallow coined grooves, 1/16 in. deep and in a square grid pattern to control fragment size in a warhead model. The warhead used was No. 142, cylindrical, 4-1/8 in. in diameter, with a 3/8 in. wall, and Composition C-3 loaded. The grid-pattern shallow grooves of Warhead No. 142 were unsatisfactory in controlling fragment size. It is believed that grooves having depths of greater than 50% of wall thickness are needed for controlling fragment size in a warhead of this design.
