Numerical Experiments on the Shock Sensitivity of Munitions
Abstract
This work is concerned with shock initiation in munitions. As a numerical experiment, twenty computations have been performed to simulate three basic types of detonation transfer between munitions at small separations. All computations show two distinct reactive flows, with shock waves communicable between them. The numerical aspects of these can serve to explain the mechanism and development of the detonation phenomena. One after the other, shock impulses arrive at the munition or acceptor explosive; it is the impact shock pulse, whose peak rises above the large scale gap test 50% point, that builds up to detonation. Shock sensitivity of the munition decreases as casing thickness or interround separation increases. Our numerical experiments also demonstrate the remarkable efficacy of thin plastic shields in suppressing detonation transfer.
