Abstract
Plastic flow, heat generation by shear force, and temperature distribution during the FSW process were analyzed. The plastic flow was numerically calculated using a particle method and the temperature distribution was calculated using a finite element method. Both analyses were combined. Temperature distributions were calculated by changing conditions of heat generation caused by the friction between the rotating tool and the metal plates. Local temperature distributions near the rotating tool differed for the conditions, but whole temperature distributions were almost same. In the calculation result of the plastic deformation, the heat generation by the shear force occurred about 60% at near the shoulder and 40% at near the pin of the tool.
