Fatigue Equivalent Stress State Approach Validation in Non-conservative Criteria: a Comparative Study

open access: yesLatin American Journal of Solids and Structures
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.
