Description
Finite element models of the friction stir welding of aluminium alloys are reviewed and the results compared with experimental measurements. Contact between the pin and the workpiece is considered in two ways: frictional contact; or assuming the material along the contact interface rotates with the pin, possibly at a reduced speed. Models have been created using an arbitrary Lagrangian-Eulerian finite element formulation processed by commercial software, and using experimentally determined temperature distributions to reduce simulation time. Issues discussed include: material flow patterns; material velocity distributions in different weld zones; stress and strain fields; and the formation of weld zones and layered microstructures.
