Abstract : We have performed detailed theoretical and numerical investigations concerning the nature of regions that arise when energy is quickly deposited in a small domain, i.e., by impact or explosion. Such situations naturally lead to inhomogeneous, spatially dependent probability of microfracturing which is diminishing with the distance from the center of the zone where the energy was released. The appearance of critical boundaries of fragmentation and of connected fracture is a direct consequence of this decaying field of crack probabilities. jg p.4
