Abstract Damage of tribo-fatigue system it is defined on the basis of model of a deformable firm body with dangerous volume. It is shown that such volumes can be calculated on many and various parametres characterising a mechanical condition (components, intensity, stress tensor, etc.). Classification of measures of damage which can be useful in different conditions is given. Conditions of deformation are considered and some criteria for restriction of dangerous volumes are offered. Techniques and results of calculation of dangerous volumes and damage are resulted at contact interaction with a friction. Examples of use of the developed concept for the decision of almost important problems are given.

Abstract In the article on the basis of experimental data to investigate the mechanism of nucleation and crack development in the vicinity of defects in static tensile sheet elements of mild steel. It is shown that the destruction is initiated by the initial crack of a parabolic shape, emerging from defects in design-technological origin. Based on the correlations found that the shape and size of the initial cracks are determined by the volume of plastically deformed material at the base of the defect and the physical and chemical processes taking place in this volume. By using infrared heat deformation shows that the material of a deformable element for loading the formation of blocks with different stress-strain state. It is suggested that the development of initial cracks in elastically strained unit determines its brittle fracture and crack propagation along the trajectories of maximum shear stress leads to ductile fracture specimen.
