It has been documented that heat is generated during friction stir processing. The amount of heat generated between the shoulder and the work piece during friction stir processing dictates the quality of the processed zone. Hence understanding the distribution of heat and obtaining the temperature contours will assist in understanding the general process of friction stir processing. In this thesis a three dimensional heat transfer model has been developed to obtain the temperature distribution in the work piece. An example problem was solved to understand the method of solving a transient heat transfer problem using ANSYS. The developed finite element model was validated by comparing the simulation results with experimental data from five different papers. A parametric study was carried out to understand the variation in temperature for different rotational and translational speeds. The variation of temperature with respect to thermal conductivity, specific heat and density was developed. A trend line equation which predicts the peak temperature attained during friction stir processing was also developed. The predicted peak temperature is used to obtain the temperature contours through out the work piece. / A Thesis submitted to the Department of Mechanical Engineering In partial fulfillment of the requirements for the degree of Master of Science. / Spring Semester, 2006. / March 17, 2006. / Includes bibliographical references. / Peter Kalu, Professor Co-Directing Thesis; Namas Chandra, Professor Co-Directing Thesis; Juan Carlos Ordonez, Committe Member.
