Abstract A new non-linear accumulate damage model was derived from the concept of equal failure probabilities under different stress levels. Based on this model,a method of calculating fatigue reliability under complex loading was obtained when the fatigue life is obeying logical normal distribution. At last, the calculating formulas were discussed when the P-S-N curve is described as a power function or an exponential function.Correspondent: HAN Yumei, research assistant, Institute of Corrosion and Protection of Metals, Chinese Academy of Sciences, Shenyang 110015
