In this study, a numerical model for FSW has been developed. The model uses particle method.
This model can qualitatively express the plastic flow around the tool. This moel can be applied to several joint.
In this presentation, results for dissimilar lap joint is discussed.
In dissimilar lap joint case (top plate is aluminum, bottom plate is SUS304),
material flow was only arose in top plate.
As a result, joining defect easily appeared behind the tool.
It is expected that a shape of the flow area has a large influence on the occurrence of the joining defect.
