| Abstract Scope |
The fatigue tests of self-piercing riveted joints of AA5052 aluminium alloy were carried out by axial tension-tension loading mode. The micro fracture characteristics of specimen with different parameters was analyzed by scanning electron microscopy and X-ray spectrometer, and the fatigue property as well as fretting damage failure mechanism of SPR joint were studied. The results show that the fatigue cracks occur in the fretting damage area where stress concentration exist. The form and the distribution of the fretting crumbs are important factors which affect the fatigue property of joint. Within the value range, the fatigue life prolongs with the increase of stress ratio, however decrease with the increase of loading level adopted. The fatigue property differs between different riveting direction, and better strength property could be obtained when the rivet direction reverse. |
