A FRACTURE MECHANICS APPROACH TO ROLLING CONTACT FATIGUE

Abstract Linear elastic fracture mechanics were used in the study of development of subsurface cracks in rolling contact fatigue. It is clear that such cracks are able to propagate by a shear mode, but it is suggested that the development of residual tensile stresses perpendicular to the wear surface may well result in a more important mode of growth which occurs when the load has passed over the crack
