Abstract:

Appreciable compressive stresses develop during tensile fatigue RO of normalized SAE 1040 steel, but only in or near regions of stress localization. These stresses develop in stages. After shot peening, the resultant compressive stresses are rapidly eliminated by tension-tension fatigue above the endurance limit, and replaced by tensile stresses. At lower stress levels the induced stresses fade quickly. Author
