Abstract

In this paper, the fatigue strain energy density parameter for the critical plane, proposed by Glinka et al., Fatigue Fract. Engng. Mater. Struct. 1995;18(1):37, is modified so that it can be used to predict the fatigue life of various materials under multiaxial loading. The material constant in the modified form can be determined by two simple tests, e.g. the uniaxial and the pure torsional fatigue tests. To evaluate the modified parameter, the predicted results are compared with experimental data found in literature for SAE-1045 steel reported in Kurath et al., Multiaxial Fatigue, Analysis and Experiments, SAE, 1989;AE-14:12-32 and 304 stainless steel tested by Wu and Yang 3, J. Engng. Mater. Tech. 1987;109:107. In addition, predictions by several existing multiaxial fatigue models are also included for comparison. It is demonstrated that the modified fatigue strain energy density parameter yields the most satisfactory result.
