Abstract
A new model to estimate multiaxial high cycle fatigue life is presented in this paper. The proposed model is used for finding fatigue life of multiaxial random proportional loading by considering mesoscopic scale failure mechanism. The predicted fatigue lives by new model which consists of a new damage indicator is better than that of existing fatigue models. The experimental fatigue lives of 14 tests and theoretically predicted lives were compared. The model was verified. The proposed model predicted multiaxial fatigue model was shown a good agreement when comparing with previous models for random loadings.
