A New Method to Determine the Fatigue Limit and the p-S-N Curve

Abstract:

The performances of material fatigue can be illustrated by the S-N curve, the p-S-N curve and the fatigue limit, which are very important to engineering and the mechanical design. Recently, the author proposed a new method to determine a conditional probability density distribution surface(CPDDS) of the material, and the surface can reflects most properties of the material’s fatigue. Methods to obtain the theoretical fatigue limit and the p-S-N curve are introduced in this paper on the basis of previous study. The methods are applied on the fatigue test data of C45 steel, and the p-S-N curves that obtained by various methods are compared in this paper.
