Evaluation and comparison of several multiaxial fatigue criteria

In this paper several multiaxial fatigue criteria are reviewed. The criteria are divided into three groups, according to the parameters used to describe the fatigue life or fatigue strength of materials. They are stress criteria, strain criteria and energy criteria. Their predictive capabilities are checked against the experimental data of six materials under proportional and nonproportional loading. Among the stress criteria, the criterion of Lee is in the best agreement with the test data. Among the strain criteria, the Kandil, Brown and Miller's criterion has the best correlation with the experimental data of the materials employed. The Farahani's criterion yields the most satisfactory result among the energy criteria. Its fatigue life correlation for 1045HR steel and 304 stainless steel fell within factors of 2 and 3. respectively. (C) 2003 Elsevier Ltd. All rights reserved.
