数値解析によるFSWツール形状が材料流動に及ぼす影響の検討

抄録

The friction stir welding (FSW) is well known as the solid-state joining. Metal materials are not melted during FSW. This paper describes a novel numerical model and calculation method for visualization of material flow during FSW process on A1100 plates. In this numerical model, the particle method as Lagrange approach is mainly employed. In this paper, the numerical model is applied to two FSW processes, and tool's shape change are taken into account. The difference of the material flow around the tool is discussed.
