Abstract
Based on the strength and crack resistance tests of dolerite and gabbro–diorite samples subjected to bending as a function of loading rate, it is shown that the kinetic constants of strength in Zhurkov model have the same values in the localized and non-localized failure modes. The tests on destruction of an organic glass sample with an edge crack yield the similar results.
