[en] Friction stir welding (FSW) process is a relatively recent welding
process (patented in 1991). FSW is a solid-state joining process
during which materials to be joined are not melted. During the FSW
process, the behaviour of the material is at the interface between
solid mechanics and fluid mechanics. In this paper, a 3D numerical
model of the FSW process with a non-cylindrical tool based on a solid
formulation is compared to another one based on a fluid formulation.
Both models use advanced numerical techniques such as the arbitrary
Lagrangian–Eulerian formulation, remeshing or the orthogonal subgrid
scale method. It is shown that these two formulations essentially
deliver the same results.
