BEHAVIOR OF EXPLOSIVE SYSTEMS UNDER MILD IMPACT

Abstract

Analytical and experimental studies were carried out to increase the understanding of the behavior of high explosives under impact loads. A mathematical model was constructed assuming that a single mechanism, viscous heating, was operating during the radial extrusion of a flat explosive billet. To check the adequacy of the analytical model, the temperature profile at the explosive-anvil interface was continuously monitored using rapid response (1-5 micro sec) surface thermocouples. To extend the applicability of the IITRI- developed method for predicting impact velocities required for the initiation of the explosive components of special weapons, basic sensitivity data were acquired for 9010 PBX, Comp B-3 and 9404 PBX. The explosives were subjected to a concentrated impact load by means of a wedge-shaped loading device and to planar uniform loads having two different pulse shapes. (Author)
