Abstract

Abstract. Friction Stir Processing (FSP) is a welding form for joining metals which by traditional methods are too difficult to weld. The three-dimensional existence during FSP makes it more complicated for experimental studies. It is also expensive and time consuming for experimental observations. In calculating the data during experiments, there might have some inaccuracies. Different simulations were used to solve the difficulties but also to improve accuracy and minimize costs. It should be noted that strong distortions of the mesh could occur in the numerical simulation as the existence of huge deformations in FSPed materials. The relationship between the deforming continuum of computing regions and grid of finite is determined by numerical technique selection. Other than that, the numerical approach describes the model's ability to resolve large mesh distortions and offers correct boundary and interface resolution. The best choice for numerical technique is the main considerations during process simulation. Lagrangian and Eulerian are different examples of algorithms for continuum mechanics. One of the other techniques suggested which is Arbitrary Lagrangian-Eulerian (ALE), modifying the above methods by combining them. A comparison between the various numerical methods to FSP simulation and the implementations of each tool in the FSP phase has been addressed in this review paper. Observations showed that the Lagrangian method is commonly used in the entire structure field to model thermal behavior. Eulerian approach is rarely used to model deformation and thermal behavior but typically used for modeling the liquid’s flow. Finally, some critical issues and topics regarding FSP simulations remain to be addressed and prospects for future study are suggested.
