    FAILURE-DELAY EFFECT UNDER INFLUENCE PULSE DYNAMIC LOADS

    An analytical analysis of the failure-delay effect of a material with a crack under shock-wave pulse action is given. The effect is expressed via the possibility of material failure at the crack tip at the mom...

    Instability of Critical and Geometric Characteristics of the Fracture Zone under Spall Conditions

    Many features of dynamic fracture caused by shock-wave action are most pronounced under spalling conditions, i.e., when an intense wave pulse is reflected from a free boundary. Therefore, such material tests a...

    Effects of strain-rate strength dependence in nanosecond load duration range

    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 ...
