The plasma explosion model in studying the electric strike damage on dielectric surface by discharge plasma

In this paper, a new model of plasma explosion in solving the problem of electrostatic spark discharge is presented based on the instantaneousness of the time of an electrostatic discharge and very limited spacial range of the discharge channel. This new model is basically different from that one of heat damage. In the light of this new model, calculation has been done and analysis expressions of distribution of stress has been obtained. This calculation result is relatively satisfied in the comparison to the result of our experiment.
