There is a need to find a proper mathematical or theoretical model regarding the FSW process parameters performance such as the tool shape, tool speed, feed rate, and axial force. Choosing suitable input parameters to obtain the desired output for different welding materials is required. It will...
The defor- mations are happened due to the high axial force while plunging the tool into the steels and high ductile-to-brit- tle transition temperatures of the tool material. Due to these all problems, these metals were replaced by a new refractory tool material, tungsten-rhenium (W-25%...
In the initial stages of welding steel through FSW, molybdenum and tungsten tools were adopted. The main limitation of these FSW tools is that they are fractured and deformed during plunging into steels [26]. The deformations are happened due to the high axial force while plunging the tool int...
The reason for subjecting the tool to repeated plunge cycles is that the tool usually experiences the maximum axial load (or forge force) and spindle torque during this stage as the workpiece is not hot enough for easy material flow before the shoulder fully engages with the workpiece and ...
tool. A consolidated joint is then formed by moving the tool along the joint line [3], as shown in Figure1. Huge axial downward force is necessary to maintain a steady joining process [4]. Maintaining this force requires a very rigid FSW machine structure, especially when joining thick ...

Friction Stir Welding (FSW) is the most promising solid-state metals joining method introduced in this era. Compared to the conventional fusion welding methods, this FSW can produce joints with higher mechanical and metallurgical properties. Formerly, FS
While the application of the Smoothed Particle Hydrodynamics (SPH) method for the modeling of welding processes has become increasingly popular in recent y
Finally, the load level is obtained by applying the well-known formula of the S-N curve, Eq. (7) or Eq. (8), with the identified parameters from the linear regression calculation. $$ \log \left(\mathrm{N}\right)=\log \left(\mathrm{C}\right)-\mathrm{m}\cdotp \log \left(\De...
