![عکس صفحه اول مقاله: Analytical and experimental investigation of fatigue and fracture behaviors for anti-double dog-bone riveted joints Analytical and experimental investigation of fatigue and fracture behaviors for anti-double dog-bone riveted joints](/preview/png/769296.png)
Load-transferred experiments and fatigue tests of the anti-double dog-bone riveted joints were carried out, and the fracture surfaces were observed by scanning electron microscopy (SEM) in this paper. Based on the finite element analysis (FEA), the multi-axial fatigue life of the anti-double dog-bone riveted joints has been predicted by Smith–Watson–Topper (S–W–T) method and Wang–Brown (W–B) method respectively. And the results of FEA were compared with the experiment results. The results show that because of the deformation of the rivets and the holes, the load transferred by the rivets decreases with external load increase. The fracture of joints all occur at rivet holes, and the crack initiates at the dog-bone specimen closed to the rivet head. Compared with the result of W–B method, the result of S–W–T method is more conservative and reliable.
