FATIGUE RELIABILITY ANALYSIS UNDER TWO STAGE LOADING

Based on two-dimensional probabilistic Miner's rule, a new method of fatigue reliabilityanalysis under two-stage loading is established, and a very successful experimental verification is made in terms of eight large samples of low-high as well as high-low two-stage fatigue experimental data given by Tanaka, et al.For a two-stage cyclic loading, let the first loading level be denoted by (Sa1, Sm1), and the second level by (Sa2, Sm2). Each individual in the specimen population is first subjected to n1 cycle...
