| Abstract: | In this paper,the concepts and methods of non equilibrium statistical physics were used to explain the statistical characteristics of electrical mechanical breakdown nucleation and propagation with the evolution equation of conducting microcrack,the probability and reliability of electrical mechanical breakdown,the average breakdown life as well as the probability density distribution function were derived in a unified form.All the results were applied to the experimental data of Al 2O 3 ceramics. |
