ABSTRACT
The peak temperature and temperature profile greatly affect the defect formation and the joint strength during the friction stir welding processing. An analytical model is proposed and tested to estimate the peak temperature based on the common constitutive equation of inverse hyperbolic sine function and the fundamentals of continuum mechanics. The calculated results of the peak temperature are consistent with the literature data of several aluminium alloys.
