Abstract
Abstract Based on the critical plane method, a high-cycle fatigue criterion considering the effects of the phase shift and mean stress on multiaxial fatigue strength is proposed for hard metals. When the materials obey the von Mises criterion and are subjected to proportional loading without the mean stress, the proposed criterion can be reduced to the von Mises criterion. The experimental data conducted under combined bending and torsion loading from some studies were employed to validate the applicability of the proposed criterion. The results demonstrate that the proposed criterion has good agreement with the experimental data under loading conditions with both the mean stress and phase shift effects.
