Abstract
The form of the time dependence is analyzed in the 10(-6)-10(-13) sec range of maximum stretching stresses in spallation and at the specific (per unit surface) fracture energy on the basis of experimental spallation data for geometrically similar specimens of a number of metals and for steel (St. 3) specimens in shock rarefaction waves. Strong scale effects of power nature were observed in metals upon spallation fracture.
