Temperature Analysis of Friction Stir Welding (AA6061-T6) with Coupled Eulerian-Lagrangian Approach.

Abstract For Friction Stir Welding (FSW), several simplified FEM models have been developed to explain key parts of thermal-mechanical phenomena. In this study, simulate the FSW process AA6061-T6 aluminum alloy, a thermo-mechanical 3-D finite element model based on Coupled Eulerian-Lagrangian (CEL) approach is used. The CEL method combines benefits both Lagrangian and Eulerian approaches, allowing it solve large-scale deformation issues. Abaqus/CAE software used stages using Johnson–Cook material law Johnson-Cook failure model. estimate parameters model's boundary conditions rigid tool. Thermocouples were installed in appropriate positions plate, temperature correlated with simulation results. generated during plunging, dwelling, welding 80% 90% melting being evaluated. experimental data was obtained from HMT made CNC (Siemens) operated VMC same compared results overall simulation.
