On the evolution and comparison of multiaxial fatigue criteria

摘要

This paper opens up with the definition of some fatigue criteria for multiaxial cyclic loading. This introduces the problem of the prevalence of random multiaxial loading in the service environment of mechanical components. Following this introduction, a survey of fatigue criteria found in the literature is presented. A comparative analysis of some fatigue models is also presented. This analysis suggests that the selection of a fatigue criterion be based on whether or not the principal directions of stress tensors are mobile or invariable with time.
