Abstract

Life prediction of parts under complex loads has always been an important research topic in mechanical engineering design. In order to make the results more accurate, the stress correction formula for the asymmetric cyclic stress is derived mixed strength degradation law and the characteristics of 45 steel in this paper. The final results indicate that linear strength degradation model established in this paper can describe the strength degradation law of the fatigue process well.
