New Nonlinear Damage Law by Fatigue Based on the Curve of Bastenaire

Abstract

This article focuses on the improvement of the nonlinear damage law by fatigue of Chabobe. It is a solution to the dependency problem of parameters of the law vis-à-vis the SN curve of the material used for their production. The determination of the parameters, or wedging of the law, has the drawback of smoothing by linear regression the points of SN curve in a particular space specific to the law, called wedging space. So doing, the law is based on the regression line points, different from the actual SN curve of the material. The evolution of fatigue damage and hence the lifetime are then modified. The main idea is to develop a new damage law model, such as the SN curve generated by this formalism is identical to the one used to describe the fatigue behavior of the material under constant amplitude. In the present case, it’s obviously the SN curve of Bastenaire model.
