Explosives and Terminal Ballistics

NEWMARK Department oj Civil Engineering, University oj Illinois • PMblished May, 1946 by HEADQUARTERS AIR MATERIEL COMMAND PUBLICATIONS BRANCH, INTEJtJYiE~9) '1001 WRIGHT FIELD, DAYTON, OHIO V-46579 The AAF Scientific Advisory Group was activated late in 1944 by General of the Army H. H. Arnold. He se cured the services of Dr. Theodore von Karman, re nowned scientist and consultant in aeronautics, who agreed to organize and direct the group. Dr. von Karman gathered about him a group of Ameri can scientists from every field of research having a bearing on air power. These men then analyzed im portant developments in the basic sciences, both here and abroad, and attempted to evaluate the effects of their application to air power. This volume is one of a group of reports made to the Army Air Forces by the Scientific Advisory Group.

Chapter 2 EXPLOSIVES
Chapter 2 EXPLOSIVES This chapter classifies commercial blasting compounds according to their explosive class and type. Initiating devices are listed and described as well. Military explosives are treated separately. The ingredi- ents and more significant properties of each explosive are tabulated and briefly discussed. Data are sum- marized from various handbooks, textbooks, and manufacturers’ technical data sheets. THEORY OF EXPLOSIVES In general, an explosive has four basic characteristics: (1) It is a chemical compound or mixture ignited by heat, shock, impact, friction, or a combination of these conditions; (2) Upon ignition, it decom- poses rapidly in a detonation; (3) There is a rapid release of heat and large quantities of high-pressure gases that expand rapidly with sufficient force to overcome confining forces; and (4) The energy released by the detonation of explosives produces four basic effects; (a) rock fragmentation; (b) rock displacement; (c) ground vibration; and (d) air blast. A general theory of explosives is that the detonation of the explosives charge causes a high-velocity shock wave and a tremendous release of gas. The shock wave cracks and crushes the rock near the explosives and creates thousands of cracks in the rock. These cracks are then filled with the expanding gases. The gases continue to fill and expand the cracks until the gas pressure is too weak to expand the cracks any further, or are vented from the rock. The ingredients in explosives manufactured are classified as: Explosive bases. An explosive base is a solid or a liquid which, upon application or heat or shock, breaks down very rapidly into gaseous products, with an accompanying release of heat energy. -
