In this paper, a quantitative prediction method for the fatigue limit reliability is proposed by using statistical characteristics of hardness in a small region and mechanical condition in a small region based on a defect size distribution and a certain stress applied to a defect. And rotating bending and push-pull fatigue under R=-1 are carried out on quenched-tempered 0.5% carbon steels, whose average hardness is about Hv≃600. Comparing a predicted fatigue limit reliability with experimental data, the applicability of the present proposed method is examined and confirmed.
