Abstract:
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 speed of sound in aluminum. It is assumed that such results are related to the strong nonequilibrium process of medium perturbation in which physical constants of material lose their meaning.
