Dynamic fracture is a time-dependent phenomena in which the spall stress depends on the stress pulse duration. It is shown that the empirical relation between the spall stress and the square root of the stress gradient is equivalent to a simple impulse criterion. A more general criterion based on th
For the voids coalescence type of fracture of elastic-plastic material, the parameter of critical void growth rate and related criterion have been developed by Zheng and Radon. This criterion has an obvious microscopic physical meaning and can be determined by macroscopic method. In the present pape
