The present study investigates thermo-mechanical issues associated with the dissimilar friction stir welding process of AA6061 and AA5086 aluminum alloys through smoothed-particle hydrodynamics (SPH) simulation experimental investigations. results demonstrate that presented model accurately predicts thermal history during process. Furthermore, both data indicate when alloy is located on advanci...

It is well known that the residual stress of the friction-stir-welded joint affects the fatigue strength and life, and the corrosion performance. In this paper, a three-dimensional finite element model is established to study the thermal history and stress evolution in the butt welding of aluminium alloy 6061-T6, which will comprehensively provide insight into the friction-stir-welding process....

In this paper, new numerical modeling of material flow in the thermo-mechanical friction stir welding process is presented. In this numerical model, the discretization in space is derived by the meshfree Galerkin method using a Lagrangian meshfree convex approximation. The discrete thermal and mechanical equations are weakly coupled as the time advances using a forward difference scheme. A mort...

the objective of this study was to develop a numerical model for the prediction of temperature distribution, effective plastic strain distribution, and especially material flow in friction stir welding of copper plates. the deform-3d software was used by incorporating a lagrangian incremental formulation. threedimensional results of the material flow pattern which were extracted using the point...
