Friction Stir Welding (FSW) is a novel kind of welding for joining metals that are impossible or difficult to weld by conventional methods. Three-dimensional nature FSW makes the experimental investigation more complex. Moreover, observations often costly and time consuming, usually there an inaccuracy in measuring data during tests. Thus, Finite Element Methods (FEMs) has been employed overcome complexity, increase accuracy also reduce costs. It should be noted that, due presence large...
