A multiaxial fatigue life prediction model was proposed based on the maximum Even if these recent investigations provide useful insights about the multiaxial fatigue response of AM parts
A Review on Fatigue Life Prediction Methods for MetalsFor the multiaxial fatigue life prediction, critical plane approaches linked to the fatigue damage of the material can be found in literature; these approaches are based either on the maximum shear failure plane or on the maximum principal stress (or strain) failure plane .
At present, most multiaxial fatigue life prediction models can accurately predict the fatigue life under proportional loading conditions. 2,10 12 But the principal axes of strain rotate continuously under non-proportional loading, and the microstructure and slip system of material change, which leads to additional hardening effect. 13,14 It
Damage Accumulation Assessment in Multiaxial Random understood, and fatigue life is reasonably estimated. However, for multiaxial fatigue, which consists in the combination of stresses acting in two or more axes, is yet to be fully understood. Damage mechanisms depending on stress combinations, loading interaction effects,

Multiaxial and Uniaxial Fatigue Failure Evaluation Using Sep 25, 2020 · As expected, the specimens show a faster fatigue failure under multiaxial loading. The mean fatigue life for the uniaxial case is 562.8 s and for the multiaxial case 496.7 s. Thereby, the detected uniaxial fatigue lives roughly range between 500 s and 700 s and are assumed to follow a normal distribution.
