Zusammenfassung:Based on Manson-Coffin Equation, a strain fatigue reliability model was built. Because of high nonlinear degree, the first-order reliability method has convergence difficulty for the model. An efficient iterative algorithm for strain fatigue reliability is proposed by using automatic step adjustment method etc., and the numerical results show that the proposed method has a good convergence compared with FORM.
