Background/Objectives: The objective of this paper is on developing a thermo-mechanical model to predict the thermal histories of the FSW butt joint of AA 6061-AZ61. Methods/Statistical Analysis: The FEM model is developed for the temperature and residual stress characteristics of the weld material. The friction serves as the heat source which exists between the pin and plate as well as the shoulder and plate. To understand the dynamics of the Friction Stir Welding thermal and residual effects,the thermal history and the evolution of longitudinal, lateral residual stresses in the friction stirred weld are simulated using ANSYS. Findings: The temperature influences on Von-mises stress and strain on the different zones are analyzed. The contour technique using Coordinate Measuring Machine (CMM) is used to measure the residual stress of the welded plate.It is found that the proposed model is correlated with experimental result. Application/ Improvements: The developed FEM model can be used as one of the tool for correlating the temperature and residual stresses on the weld zone. The CMM also can be used to predict the residual stresses through contour measurement.Keywords
