18-8ステンレス鋼の被害曲線について

抄録

French's damage line, which shows the degree of the damage by overstress on the fatigue limit, has little significance when we discuss the damage on the fatigue life. So one of the authors proposed a new damage line for fatigue life aiming the investigation of the fatigue damage, and obtained some examples with carbon steels. Consequently, the new damage line proved to be very different from French's one in shape. In this study, we obtained the same damage line for fatigue life of 18-8 stainless steel as of carbon steels, and found that the damage line for fatigue life was nearly equal to French's damage line except near the judging stress.
