Blog Article

Abstract This paper is concerned with the fatigue Table Paper prediction models for estimating the multiaxial fatigue limit.An equivalent loading approach with zero out-of-phase angles intended for fatigue limit evaluation under multiaxial loading is used.Based on experimental Hidden data found in literatures, the equivalent stress is validated in Crossland and Sines criteria and predictions compared to the predictions of existing multiaxial fatigue; results over 87 experimental items show that the equivalent stress approach is very efficient.
