Dynamics of electro burst in solids: II. Characteristics of wave process

The wave dynamics of a tensely deformed state of a solid material is analysed on plasma discharge channel formation in it at electro burst. Various mechanisms of slabbing cavity formation in the solid have been considered by means of the physical and mathematical model which consistently describes the pulse generator operation, plasma channel expansion and shock waves generation. In less power-intensive mode which is realized by the waves reflected from a solid surface and more power-intensive mode in which function of crack formation is carried out by a direct wave of compressive stresses, the most effective conditions for the destruction of the processed material have been found. The connection of the discharge circuit parameters of the pulse generator with the tensely deformed solid state and fracture pattern has been shown; influence of the material surface geometry and circuit parameters on the mode of possible destruction has been presented.
