| Abstract Scope |
Friction stir welding (FSW) is a solid state joining process that uses frictional heat generated by a rotating tool to join materials. Yet, the tool role in the material processing, due to complex material flow and its difficult modeling, is still not entirely understood. In this matter, a computational solid mechanics numerical model aimed to simulate the FSW process in an AZ31 alloy is proposed. This model uses an Arbitrary Lagrangian-Eulerian code in two different pin profile tools, with threaded and unthread pins. Point tracking technique was applied in the model to provide deformation, velocity and temperature data both conditions. It was noticed that velocity and strain rate have higher values in the threaded condition. Finally, the point tracking data was applied in a grain size model and compare to the real microstructure, showing good consistency of the predicted temperature and deformation behavior calculated by the model. |
