Changes in Residual Stresses during Tension Fatigue of Normalized and Peened SAE 1040 Steel.

Abstract

Appreciable compressive stresses develop during tensile fatigue (R=O) 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)
