Abstract Scope |
High-Velocity Riveting (HVR) is a novel joining method that allows the joining of two sheets of metal through a metallurgical bond resulting from the high-speed impact with the rivet and the die. Different combinations of Aluminum Alloys (AA6061-T6, AA7075-T6, and AA5052) were joined using HVR and resulted in lap-shear joint performance outperforming conventional riveting, clinching, and adhesive bonding. We present a 3D finite element (FE) model used to help inform the die design and processing conditions. The model was able to simulate the joining process and results at the interface between the joined sheets suggested that high pressures and temperatures lead to joints with superior performance. Model findings in terms of joint cross-sections, and lap-shear performance are in good agreement with the experiments. Parametric studies on rivet material, rivet shape, and die design were conducted and analyzed to inform the process development and achieve high-quality joints. |
