- Brisance
Brisance is a measure of the rapidity with which an
explosive develops its maximumpressure .In addition to strength,
explosive material s display a second characteristic, which is their shattering effect or brisance (from the French "briser", to break), which is distinguished from their total work capacity. This characteristic is of practical importance in determining the effectiveness of an explosion in fragmenting shells,bomb casings,grenade s, structures, and the like. The rapidity with which an explosive reaches its peak pressure is a measure of its brisance. A brisant explosive is one in which the maximum pressure is attained so rapidly that ashock wave is formed, and the net effect is to shatter (by shock resonance) the material surrounding or in contact with the supersonic detonation wave created by this explosive. Thus brisance is a measure of the shattering ability of an explosive.The sand crush test is commonly employed to determine the relative brisance in comparison to TNT. No single test is capable of directly comparing the explosive properties of two or more compounds;Fact|date=November 2007 it is important to examine the data from several such testsFact|date=November 2007 (sand crush, trauzl, and so forth) in order to gauge relative brisance. True values for comparison will require field experiments.Fact|date=November 2007
One of the most brisant conventional explosives is cyclotrimethylene trinitramine (also known as
RDX ). [cite book|title=TM 9-1300-214|publisher=US Army]References
