ABSTRACT
The purpose of the review of experimental and theoretical data presented in Sections 8.2, 8.3, and 8.5 is to describe the modern understanding of experimental results and theoretical modeling of the contact fatigue phenomenon and other phenomena related to contact fatiguethat occur in different materials under various loading and environmental conditions. Section 8.4 illustrates the improvement in estimating fatigue life of radial ball bearings by introducing the dependence of fatigue life on friction. This review creates a realistic basis for the further analysis of the existing mathematical models of fatigue life for bearings and gears in Section 8.6.
