Abstract:

Theories of dielectric breakdown are examined for application to explosive materials. It is found that breakdown theory in inerts can be used to model and predict breakdown fields in explosives in a low temperature regime. In a higher temperature regime, breakdown theory in explosives must be modified to account for the exothermic kinetics. The relationship between thermal breakdown and thermal explosion theory is discussed and numerical solutions to the heat transport equation are obtained and analyzed.
