Prediction for multiaxial fatigue strength with small defects

Abstract

As an extension of previous studies, this paper further examine the applicability and characteristics of the predictive method, in particular, for the case of proportional loading. The predictive method is based on the \vec{area}-parameter model and Endo's biaxial fatigue failure criterion. The present study manifests that the critical plane is normal to the direction of maximum principal stress, and the fatigue strength is dictated by both the maximum and minimum principal stresses. © Owned by the authors, published by EDP Sciences, 2014.
