3D Numerical Simulation of Linear Friction Welding of Mild Steel Based on ABAQUS
In this work, a 3D numerical model was developed to investigate the complicated thermo-mechanically coupled process of Linear Friction welding (LFW). The explicit-implicit alternate method was for the first time adopted to simulate LFW of mild steel based on the ABAQUS software. To cope with the excessive element distortion, remeshing was conducted at certain calculation time with the help of the HYPERWORKS software. Results show the temperature at the interface is quickly increased to near 900 刟C at 1s. With increasing the welding time, the joint reaches a quasi-steady state where the interface temperature maintains at about 950刟C and the axial shortening rate keeps constant. Moreover, the effects of processing parameters (oscillation frequency, oscillation amplitude and friction pressure) on the joint temperature evolution and axial shortening were systematically examined and discussed.
