Abstract: The model describing elastic wave propagation and cracks formation under action of the expanding discharge channel is presented. Results of simulation of solid material destruction by discharge channel which located near the free sample surface are presented. The work is supported by grant RFFI (08-08-01016-а)

Keywords: pulse generator, plasma channel, deformation, destruction, simulation.
