Brisance of the high explosives

Włodarczyk E.

Journal of Technical Physics

2000

Vol. 41, no 4

343-359

The essential survey of the literature data, concerning the brisance of high explosives (HE) has been made in this paper. It is confirmed that the quantitative criteria of the theoretical estimate of the HE brisance proposed in the scientific literature are based on several assumptions, which are contradictory to the real course of the explosion phenomenon, and therefore they are erroneous. These criteria must not be applicated in the engineering practice. The reflection process of the detonation wave from th inertial rigid partition was used in order to derive the new formula describing the relative brisance of the HE. Moreover, the brisance of numerous commercial explosives and the military ones has been analysed too. The results, presented in this paper, are confirmed by experimentally gained data.
