AB  - Friction stir welding (FSW) of polymeric materials has recently attracted 
      significant attention. Herein, we present the effect of the tool pin profile on 
      the FSW of high-density polyethylene (HDPE) joints through joint experimental 
      analysis and thermomechanical simulations. For analysis of pin profile effects on 
      the thermomechanical properties of HDPE joints, frustum (FPT), cubic (CPT), and 
      triangular (TPT) pin shapes were selected in this study. This research 
      investigated the heat generation of the parts of the different tools as well as 
      heat flux (internal and surface). The results revealed that the heat generation 
      in pins with more edges (cubic (96  degrees C) and triangular (94  degrees C)) was greater than 
      in pins with a smooth shape (frustum (91  degrees C)). The higher heat generation caused 
      the heat flux on the surface of the HDPE from the cubic pin profile to be greater 
      than for other joints. Due to the properties of HDPE, higher heat generation 
      caused higher material velocity in the stirring zone, where the velocity of the 
      materials in TPT, CPT, and FPT pins were 0.41 m/s, 0.42 m/s, and 0.4 m/s, 
      respectively. The simulation results show sharp-edged pins, such as triangular 
      and cubic, lead to over-stirring action and internal voids formed along the joint 
      line. Furthermore, the simulation results indicated that the size of the stirred 
      zones (SZs) of the FPT, TPT, and CPT samples were 17 mm(2), 19 mm(2), and 21 
      mm(2), respectively, which is around three times the corresponding values in the 
      HAZ.
