Abstract:

Numerical modeling of complex processes with very large deformations, such as encountered in forging are fully established now. With the development of automatic re-meshing algorithms for both 2D and 3D finite element meshes, computer programs are able to simulate the forging of complex 3D parts. However, the Lagrangian formulation normally used does not allow them to handle more intense deformations, such as those that take place in Friction Stir Welding (FSW) or Friction Stir Processing (FSP).  Hence, the Arbitrary Lagrangian Eulerian (ALE) formulation was extended and enhanced to simulate FSW. However there is a great need to establish numerical modeling techniques for production of Nano-composites with FSP. In this talk Experimental Studies and Numerical Modeling of Friction Stir Welding (FSW) and Friction Stir Processing (FSP) with some of the issues and challenges involved in numerical modeling will be discussed.
