| 主要内容：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 analysis. The randomness of loading and the theory of fatigue damage accumulation (TOFDA) are considered. The probabilistic analysis of local stress, local strain and fatigue life are constructed based on the first-order Taylor''s series expansions. Through this method proposed fatigue reliability analysis can be accomplished. |
