N2 - The latest results connected with application of the incubation time approach to problems of dynamic fracture of brittle materials including rocks and concretes are summa-rized. The incubation time based fracture criteria for intact media and media with cracks are discussed. Available experimental data on high rate fracture of different rock materials and in-cubation time based fracture criteria are used in order to evaluate critical parameters causing fracture in these materials. A unified interpretation of rate effects based on the structural-temporal approach is presented. It is shown that the temporal dependence of the dynamic spall strength and split tensile strength can be predicted by the incubation time criterion. It is shown that in spite of the fact that static strength of one material is smaller than that of another one, its dynamic strength measured in terms of the incubation time can be essentially higher. By com-paring static and dynamic strength, it is possible to optimize (minimize) the energy
