Modelling and simulation of FSW of polycarbonate using Finite element analysis

Friction stir welding of polycarbonate was successfully prepared and simulations were performed using Finite element analysis in order to examine the effect on material properties of parameters. Multiple iterations were carried out with changing parameters to determine their effects on the results. The heat-affected zone was generally small. Increasing heat input resulted in larger heat affected zone. There was no formation of affected zone of thermo-mechanically in the weld line, due to limiting the heat dissipation. This also results in localization of heat around the joint line on the top surface. Lower heat inputs resulted in lower strain rate which give rise to cracks around the joint line increasing tool rotational velocity results in larger stir zone (plasticized area). Increasing heat input resulted in decreased material viscosity which may lead to material removal from the workpiece. Copyright (C) 2021 Elsevier Ltd. All rights reserved.
