Abstract :
Disintegration tests with specimens of yellow sandstone showed that there exists an optimum amount of energy, which in electrical field in excess of the dielectric strength at solids, produces disintegration of material with minimum of energy per unit volume of the solids. This optimum energy absorbs during the one half of the pulse wave and generates the electrical breakdown and the mechanical disintegration of solids. The position of path of the discharge in solid-liquid system depends on electrical and mechanical parameters of the liquid-solid system
