Fatigue reliability analysis under two-stage loading

On the basis of the two-dimensional probabilistic Minerʹs rule, a new method of fatigue reliability analysis under two-stage loading is established. Eight large samples of testing data under low–high and high–low two-stage cyclic loading are used in the experimental verification. It is showed that the reliability-based predictions of the residual fatigue life as well as of the total fatigue life agree very well with the experimental results.
