Abstract:A new Eulerian model is established based on solid mechanics. With comparisons to the experimental data and the ALE model, the current model is validated. The power and the heat generations from pin side surface, pin tip surface, and shoulder contact surface in different rotating speeds are studied. Results indicate that the ratio of the heat input powers from the pin and the shoulder keeps constant in different rotating speeds. The velocity of the material flow around the welding tool and the slipping velocity are both increased with the increase of the rotating speed. The increase of the slipping velocity is the main reason for the increase of the heat input with the increase of the rotating speed. The torque from the shoulder contact surface is the major part of the total torque. The contribution to the total torque from the pin tip surface is the smallest.
