Instability effects of the dynamic crack propagation process

•Stress intensity factor – crack velocity dependence (K“ − ȧ) is numerically studied.•Space-time discreetness of the dynamic fracture is the fracture process feature.•Incubation time fracture criterion is applied.•Scatter of the K“ data defines possibility of the K” − ȧ curve construction.•Various...
