Abstract
Thermo-mechanical simulation of the friction stir butt welding process was performed for AA5083-H18 sheets, utilizing commercial FVM code, STAR-CCM+, which is based on Eulerian formulation. Temperature and strain rate histories along the material flow were calculated under the steady state condition and simulated temperature distributions (profiles and peak values) were compared with experiments for verification. It was found that by including proper thermal properties of the backing plate (anvil) the accuracy of the simulation results increased significantly.
