In particular, the following key elements of model are developed: criterial condition and equation of fatigue distribution of cracks under the complex stress state condition; system of the singular integral equations of a contact task of the elasticity theory for bodies with curvilinear cracks; differential construction algorithms (step-by-step) of cracks growth paths. The growth paths of the surface and presurface cracks in a contact zone have been investigated. The defects formation laws of a type of pitting ("squat") and spalling have been established Product Description popup.authors popup.nrat_date 2020-04-02 Close
