Electrical model of detonation kinetics of explosives

To verify the hypothesis of electrical hot spots – 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 were 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 experiments with liquid nitromethane and monocrystalline PENT are explained.
