ABSTRACT

Several numerical model of heat transfer analysis of aluminum alloy by FSW are available in published literatures. Like, Khandk et al. (2003) developed a three-dimensional thermal model where the heat generation was modeled based on experimentally measured torque distribution. Ulysse (2002) modeled the effects of tool speeds, both rotational and linear, on forces and plate temperatures during FSW of thick aluminum plates, based on a three-dimensional viscoplastic model. Nandan et al. reported results of a three-dimensional material flow and heat transfer model during FSW of 6061 aluminum alloy (Nandan et al. 2006). They calculated the temperature fields, cooling rates and the geometry of the thermomechanically affected zone (TMAZ). The computed temperature fields and TMAZ agreed well with the corresponding independent experimental data.
