Description
A direct modelling approach ("SAMCEF" software finite element simulation) coupled with an inverse model, based on genetic algorithm optimisation (MAX software), was applied to the friction stir welding (FSW) process for two aluminium alloys (6005A-T6 and 2024-T3), and experimental results were also obtained for temperatures, forces and torque. For the experiments, butt welds were produced on plates (6 mm thickness) and measurements were taken using a dynamometer and thermocouples at various positions. The finite element model involved a sequential thermal-mechanical analysis including contact between meshed tool, workpiece and backing plate. The optimisation module identified heat input and contact conductivity. Experimental and simulated temperature-time histories were compared, and simulated residual stress distributions are presented.
