Fatigue Test Research for SPR Aluminum Alloy Sheet

摘要：

　　In this paper,the fatigue behavior of self-piercing riveting (SPR) joints is compared with resistance spot welding (RSW) joints for the same A6063 aluminum alloy sheets.The fatigue test,where every specimen is tested under different load,is conducted on MTS810.23M testing machine,and the results show that SPR joints have superior fatigue performances.Next S-N curve of every specimen is deduced after regression analyses of test data and the fatigue damage rule of SPR aluminum alloy sheets is summarized.Finally the effect of test parameters and errors on fatigue life of RSW and SPR joints is evaluated with two-factor and multiple factor analyses of variance.
