The Effect of Tool Geometry on Material Flow Behavior of Friction Stir Welding of Titanium Alloy
Article history: Received 1.11.2012 Received in revised form 10.12.2012 Accepted 10.12.2012 Based on the RNG k-ε model, the finite volume model of friction stir welding of Ti6Al4V alloy is established by ANSYS FLUENT software. The effect of rotational tool geometry on titanium alloy flow behaviour is exhibited. The results of numerical simulation show that the flow direction of material near th...
متن کاملMaterial Flow Visualization in Friction Stir Welding via Particle Tracing
This work deals with the modeling of the material flow in Friction Stir Welding (FSW) processes using particle tracing method. For the computation of particle trajectories, three accurate and computationally efficient integration methods are implemented within a FE model for FSW process: the Backward Euler with Substepping (BES), the 4-th order Runge-Kutta (RK4) and the Back and Forth Error Com...
متن کاملCoupled Eulerian-Lagrangian (CEL) Modeling of Material Flow in Dissimilar Friction Stir Welding of Aluminum Alloys
In this work, the finite element simulation of dissimilar friction stir welding process is investigated. The welded materials are AA 6061-T6 and AA 7075-T6 aluminum alloys. For this purpose, a 3D coupled thermo-mechanical finite element model is developed according to the Coupled Eulerian-Lagrangian (CEL) method. The CEL method has the advantages of both Lagrangian and Eulerian approaches, whic...
متن کاملEffect of Tool Pin Threat on the Material Flow and Mechanical Properties Friction Stir Welding of 6061 Aluminum Alloy to Copper
Dissimilar joint with good quality and mechanical properties is one of the major problems the industries. One of the most commonly used methods to solve this problem is friction stir welding process. In this paper two different tool pin with simple cylindrical and screwed profile were used to finding optimization of friction stir welding parameters to reach best mixing flow, composite structure...
متن کاملOptimization of Friction Stir Welding Tool Advance Speed via Monte-Carlo Simulation of the Friction Stir Welding Process
Recognition of the friction stir welding process is growing in the aeronautical and aero-space industries. To make the process more available to the structural fabrication industry (buildings and bridges), being able to model the process to determine the highest speed of advance possible that will not cause unwanted welding defects is desirable. A numerical solution to the transient two-dimensi...
