Nowadays, the estimation of fatigue life under multiaxial random loading is still an extremely complex task. In this paper, a comprehensive review of the multiaxial random fatigue criteria available in the literature is presented. Such a review is mainly devoted to stress‐based criteria for the evaluation of fatigue life in high‐cycle regime. Time and frequency domain approaches are examined. The focus of this paper is related to uniform stress/strain distribution, but also the effect of stress/strain gradient is tangentially addressed. More than 200 references are cited.

Another difficulty involves their implementation for general complex multiaxial fatigue loading that permits arbitrary stress histories such as the variation of the principal stress directions during the stress cycle history (Lambert et al (2010); Soh et al (2013); Li et al (2015)). In this case, it is hard to track the path of each principal stress direction at each moment in time.…”

This paper is concerned with the fatigue 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 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.

Aiming at the flexible hinge is often affected by external random variable loading operating noise fluctuation and complex factors, the fatigue degradation or failure is lack of analysis methods and that causes weak link of fatigue life analysis is difficult to find in the engineering practice. This paper introduces fatigue analysis method combines the fatigue of rain flow counting method and Pam Glen palmgren Miner theory. The article uses random loadtime history to deal with cyclic loadings by rain flow counting method. Calculate the flexible hinge fatigue damage with the S-N curve in different stress. The fatigue life and the design of the weak link are obtained under random variable loading through simulation with ANSYS. The strategies are given to improve the anti-fatigue for rectangular flexible hinge which improve the deficiencies in the design. This method has instruction and reference value to actual project.
