Abstract:In this paper, the material flow around the pin during friction stir welding (FSW) is simulated using a 2D plane
strain model. A pin rotates without translation in a disc with elasto-viscoplastic material properties and the outer boundary of
the disc is clamped. Two numerical methods are used to solve this problem and an analytical solution is derived. The analytical
model is complementary to validate the two numerical methods, i.e. the arbitrary Lagrangian-Eulerian (ALE) method and the
adaptive smoothed finite elements method (ASFEM).
