• In this paper, the fatigue strength evaluation method by calculating theoretical cyclic plasticity size ω directly from a 3D FEM model was proposed. And the validity was checked by comparison with the 2D FEM model result in Society of Automotive Engineers of Japan. Moreover, in case of a continuous welding-bead model, it pointed out by 3D FEM method that the fatigue prediction diagram came to the high life side rather than the discontinuous welding-bead reported conventionally. And its tendency was confirmed by a fatigue experiment. Thereby, it is able to evaluate the fatigue strength for a wide range fillet welding junction.
