We consider the physicomathematical formulation of the problem of explosive formation of a penetrator from a low-sphericity copper lining. Calculations are made for the formation of a penetrator for a phlegmatized hexogen charge for two models of the

A model is proposed to determine the dynamic cracking resistance KID of metals and alloys for the case of a rapidly moving fractal or self-affine crack. The values of this characteristic correlate with the fractal dimension Df of the future contour o

This Letter presents the results of investigations of crack velocities within nanosecond pulses of loading in specimens of aluminum foil. It has been established that the crack velocities are close to, and even exceed, the values of the longitudinal
