Abstract:

Accurate simulation of material forming requires managing severe mesh distortions to preserve the geometry of the workpiece. Classical Lagrangian descriptions often become computationally expensive under such conditions. The Arbitrary Lagrangian-Eulerian (ALE) method offers a robust alternative by combining the strengths of Lagrangian and Eulerian descriptions, thereby improving computational efficiency and numerical stability.However, a major challenge remains in accurately handling free surfaces to maintain the geometric fidelity of the workpiece.This work introduces a new ALE-based approach to address this limitation. An analytical case as well as a Friction Stir Welding (FSW) case will be presented to demonstrate its effectiveness.
