Abstract
To verify the hypothesis of electrical hot spots (HSs)—channels of local electrical breakdowns—the analysis of the electrical properties of condensed explosives and the evaluation of the electric field strength in shock-loaded dielectrics are carried out. It is established that conditions for electrical breakdowns can be created in the compressed zone of explosives due to polarization phenomena (electric field) and shock-induced electrical conductivity (free electrons). The position of the electric model of detonation kinetics are formulated. The results of the experiments with liquid nitromethane (NM) and monocrystalline PENT are explained.
