| Abstract Scope |
Friction riveting (FricRiveting) is an innovative, fast, and energy-efficient process for spot-joining metal–metal structures. Although FricRiveting has been studied experimentally in recent years, its process modeling is rarely found in the literature primarily because of the associated large material deformation and extreme thermomechanical conditions. In this work, a mesh-free smoothed particle hydrodynamics (SPH) framework that can well handle the abovementioned numerical challenges is used for simulating the FricRiveting of AA5052 to AA6061. Predicted temperatures are thoroughly validated by multi-point thermocouple measurements from the experiment. Grain refinement in the vicinity of the riveting zone is further predicted using SPH outputs and validated by the EBSD data. Based on the model, process parameters are optimized which yields better performance over the baseline case. |
