The Measurement of Electrical Conductivity in Detonating Condensed Explosives

Abstract

The time-resolved measurement of electrical conductivity provides a unique means of studying detonating explosives. The results of a large number of experiments are reported. Two types of experiments were performed; they measured bulk resistance and time-resolved conductivity. Some interesting effects, due to detonation wave instabilities, were observed when the explosives dimensions were close to criticality, i.e., close to failure diameter or thickness. The conductivity profile observed in the aluminized explosive PBXN-111 (formerly PBXW-1 15) is interesting and unusual. The results are probably due to a combination of wave instabilities and late reaction effects. This demonstrates one of the advantages of using conductivity measurements as a diagnostic tool. Wave instabilities are apparent that could not be determined by other means....
