The method of singular integral equations has been effectively applied to the development of the theoretical foundations of contact fatigue of friction nodes (tribes), in particular rolling pairs. The role of transverse shear cracks in the formation of typical contact-fatigue damage in rolling bodies has been investigated. The characteristic angle (dominant direction) of propagation of the boundary cracks of the transverse displacement in the elements of rolling pairs is theoretically revealed and on the basis of it typical model-fatigue damages such as pitting, "strokes", main branches of "burrow" are modeled. Residual contact durability was estimated and contact fatigue curves for 65Г steel were constructed based on the criterion of exfoliation formation. These curves can be used to predict the contact durability of rolling pairs. Product Description popup.authors Ivantyshyn Nataliya A. Bida Nadiia M. Glazov Artem Yu. Datsyshyn Oleksandra P.
