In work the design procedure of parameters of contactless electrodischarge destruction of fragile nonmetallic materials is stated. In a technique the circuit is shown and calculations of transformation of elec- tric energy in mechanical are executed in view of transitive stages from the channel of the category through transmitting elements (the shock mechanism) up to destroyed object. On the basis of laws of physics the mathematical model of calculation of parameters of dry contactless dischage destruction of fragile nonmetal- lic materials is developed. For scientists and the technical officers occupied with development of electrodis- charge technologies.
