Application of Adaptive Element-Free Galerkin Method to Simulate Friction Stir Welding of Aluminum
Abstract The modeling of friction stir welding (FSW) is challenging as severe plastic deformation is present. This is in particular the case as typical finite element methods are employed. In this study we use a meshfree technique to model the...
