Fatigue Life Prediction for Simultaneous Stress and Strength Variances,

Abstract

Simple closed form expressions have been found to accurately predict the fatigue life of structures subjected to sinusoidal or random stresses where the applied stress and the material's strength are simultaneous random variables. With appropriate parameter value changes the same equations accurately apply to both the low cycle (inelastic) and high cycle (elastic) fatigue regions. These equations are in familiar engineering terms. Comparisons between analytical predictions and empirical results have shown to be good whenever such comparisons were made. (Author)
