| Abstract(E) | We investigated the fatigue behavior of stress raisers in stainless steel sheets and clarified the influence of coaxing on the fatigue limit. By observing differences in crack initiation and propagation depending on the stress ratio R and stress amplitude from hysteresis loops and fatigue curves, we attempted to elucidate the mechanisms of crack propagation and fracture. The location and propagation rate of cracks differed depending on the stress amplitude and R value, and it was revealed that coaxing in stress raisers affects fatigue strength and is an important factor influencing crack arrest and fatigue life. |
