Forming Quality and Fatigue Behavior of Self-Piercing Riveted Joints of DP590 and AA6061 Plates

Two kinds of self-piercing riveted (SPR) joints were prepared with DP590 and AA6061 plates. The forming qualities the studied using finite element method. relationships between fatigue life failure forms different upper plates discussed. Finally, mechanisms analyzed. results show that maximum static tension DA32 (with an plate DP590) is significantly greater than other kind, always longer AA40 when a 2.0 mm thick aluminum alloy under same load. mode SPR changes obviously due to plates, can be effectively improved by reducing microvibration wear.
