| Abstract |
On the basis of the structural-temporal approach, we explain the rapid increase in the spall strength and its stabilization in the nanosecond range of load duration, observed in several experiments. We give a detailed presentation of the method for describing the time-dependence of the spall strength. We obtain a qualitative coincidence of the computational curves and the experimental data and show that the strength significantly depends on the pulse parameters. An analysis of the obtained results allows us to conclude that it is incorrect to introduce a limit stress as the material "dynamic" strength by analogy with equilibrium processes; it is necessary to use the strength structural-temporal characteristics instead. |
