Effect of die designed geometrical parameters on riveting quality of self-piercing riveting joints in 5052 aluminium alloy.

This paper investigates the effects of die design geometrical parameters on self-piercing riveting (SPR) operations and the joint quality of 5052 aluminum alloy. Piped-die types with various designed diameters and depths were prepared. Subsequently, a 2D axisymmetric simulation model was developed to analyze the riveting efficiency and forming mechanism of SPR joints.
