Abstract: This work presents a mechanical testing and numerical simulations on fatigue behavior, in particular, the fatigue life and failure modes as well as the final fracture of metallic materials. First, the mechanical tests of the base alloys and their welded joint were conducted, and the stress-circulation curve with a survival rate was obtained. Second, the failure modes and fracture mechanism of such metallic materials were analyzed. Third, the load spectrum of the key parts of a typical welding joint was converted into stress spectrum. Finally, the fatigue life of the parts was achieved based on the finite element analysis and corresponding numerical simulations. The results showed a very promising application of such composite materials to meet the safety requirements. Therefore, the present study also provides a very practical method, which can be applied in various industrial aspects such as materials and mechanical engineering as well as structural control and safety monitoring.
