| Abstract |
This work presents an experimental investigation and a finite element analysis on mechanical behavior, in particular, the deformation behavior, fatigue performance and failure modes of metallic materials such as a grade 8.8 alloy steel. First, the mechanical tests of the base alloys and their welded joint were conducted, and the stress-circulatio 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. Therefore, the present study 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. |
