Abstract
This paper presents a numerical simulation of temperature distribution in magnesium alloy AZ31B-H24 plates due to Friction Stir Welding. For this aim, a model based on finite elements, using Lagrangian formulation is implemented in Ansys Parametric Design Language. Temperature-dependent material characteristics and a temperature-dependent coefficient of friction are implied by the model, using theoretical mathematical formulae. In addition to this, heat generation is also considered. This model is validated with the experiment and showed a good agreement. The maximum temperature results obtained are at the rotational speeds of 1500 and 1600 rpm with feed rates varying as 80,100,120 mm/min. The deviation between experimental maximum temperature and theoretical was observed as an average value of 4 per cent. The maximum temperatures are lesser than the melting point temperature of AZ31B alloy.
