Abstract Based on the critical plane approach and the analysis of the proposed fatigue life prediction model applied to the smoothing tubular specimen, the recently proposed multiaxial fatigue life prediction model is extended to assess multiaxial fatigue life for notched specimens. In addition, with the aid of finite element method (FEM), the orientation of the critical plane and the effective cyclic parameter are determined by using the coordinate transformation principle. In the meantime, the proposed model is modified when the mean stress is existence.
