Comparative study of multiaxial high-cycle fatigue-prediction criteria

Six common fatigue-prediction criteria for multiaxial high-cycle fatigue analysis were analyzed with several materials and loading data.The selected criteria cover: equivalent stress criteria,stress invariant criteria and critical-plane stress criteria in current investigations.The experimental data covered 10 kinds of metal materials,including alloy steel,low-carbon steel and aluminum alloy and cast iron,under proportional and non-proportional loading conditions respectively.The analytical results show that,the predicted results for low-carbon steel and alloy steel are better than that for other materials,and the predicted result for proportional loading is better than that for non-proportional loading.Papadopoulos criterion,Susmel criterion and Liu criterion show better prediction capability than the other three criteria.However,the prediction results of all six criteria for cast-iron materials are dissatisfactory.
