Abstract
For development of the friction welding with smaller change in shapes, the prediction of plastic flow behavior during the friction welding process is required. Plastic flow behavior of aluminium alloy with the temperature distribution was numerically analyzed dynamically. The plastic flow behavior was calculated with the finite element method for the elasto-plastic material. The change of temperature distribution was analyzed with unsteady state heat conduction equation. The analysis was conducted with various welding parameters, including the friction pressure, friction time and the speed of rotation. The results of the numerical analysis were compared with the experimental results obtained by the friction welding with the same parameters.
