The cyclic stress-strain responses (CSSR), Neuber’s rule (NR) and cyclic strain-life relation(CSLR) are treated as probabilistic curves in local stress and strain method of low cycle fatigue analy-sis. The randomness of loading and the theory of fatigue damage accumulation (TOFDA) are consid-ered. The probabilistic analysis of local stress, local strain and fatigue life are constructed based on thefirst-order Taylor’s series expansions. Through this method proposed fatigue reliability analysis can beaccomplished.
