Using the split Hopkinson tensile bar device, a series of special riveting specimens for MS20615 rivet are designed, and the dynamic mechanical tests of riveting structures are performed under different loading angles and loading rates. In addition, the quasi-static mechanical properties of riveting structures are also obtained by conducting tests of the pure shear, 30°tension-shear coupling, 45°tension-shear coupling, 60°tension-shear coupling, and pure tension. Results show that the failure modes of riveting structures are significantly influenced by the loading angles and loading rates. Moreover, using the financial software LS-Dyna, the simplified finite element models (FE models) are established. The comparisons of force-displacement curves for the experiments and simulations are conducted to verify the feasibility of the simplified model. Meanwhile, the mesh correlation analysis is also performed as a supplementary verification.
