Description
An investigation incorporating experimental measurements and thermomechanical simulations was undertaken to examine the effects of underwater friction stir welding (FSW) on an AISI 321 stainless steel sheet (thickness 3 mm) and to analyse the mechanical properties of the welded joints. FSW was performed at a rotational speed of 800 rpm, tool tilt angle of 1.5 deg. and load of 10 kN. Weldment mechanical properties were characterised by micro Vickers hardness measurements and tensile tests. Thermomechanical simulations were conducted using ANSYS 15.0 finite element simulation software, taking into account heat flow and temperature distribution. Physical properties such as stress distribution, strain distribution and total plastic deformation were calculated by coupled field analysis.
