Numerical Simulation of the Thermo-Mechanical Behavior of 6061 Aluminum Alloy during Friction-Stir Welding

In this work, a finite-element model was elaborated to simulate the thermomechanical behavior of 6061 aluminum alloy during friction-stir welding (FSW). It shown that FSW-induced deformation is two-stage process. addition stirring action exerted by rotating tool probe, material in near-surface area stir zone also experienced secondary shoulder edge after passage tool. Both steps were found be comparable terms temperature and strain, but primarily concentrated layer. The effects rotation translation rates on FSW strain systematically examined. Depending particular conditions, peak predicted vary from 360 500 °C, while cumulative effective 12 45.
