The regularities of micro-shock fatigue destruction of annealed metal materials under
severe loading conditions are revealed. Based on the law of summation of damages and taking into
account the features of crack formation in dynamically deformed volumes of wear materials, a model
is obtained for erosion. The generalization of the obtained private model at the micro - macroscale
level of wear made it possible to obtain a universal power dependence suitable for assessing the durability
of materials. The law of summation of damages for stepped loading is presented .
