A multiaxial fatigue criterion for metals subjected to random loading is presented.

Abstract

A multiaxial fatigue criterion for metals subjected to random loading is presented. Accordingly, the orientation of the critical plane, where fatigue life estimation is carried out, is determined from the weighted mean position of the principal stress directions, and a nonlinear combination of stress components acting on the critical plane is used to define an equivalent normal stress. Then, a specific cyclic counting method and a general damage model is employed to process such an equivalent stress and to determine fatigue endurance. Finally, an application of the criterion to some relevant random fatigue tests (proportional bending and torsion) is presented.
