[ 1 ] - Transient Three-Dimensional Thermal Analysis of a Slab with internal heat generation and heated by a Point Moving Heat Source

In this work, analysis of transient three-dimensional heat transfer in a slab with internal heat generation and heated by a point moving heat source along its axis is carried out using integral transforms methods. The heat input into slab or workpiece by the moving heat source is considered in the model. From the results, it was established that the temperature of the material during the heat t...

[ 2 ] - Analytical Investigations of the Effects of Tool Pin Profile and Process Parameters on the Peak Temperature in Friction Stir Welding

In this work, effects of different tool pin profiles of flat and tapered shoulder geometries on the peak temperature in friction stir welding are investigated analytically. The developed models used for the analytical investigations considered the welding process as a combination or mixture of the pure sliding and the pure sticking. From the results, the amount of heat generation and the peak t...

[ 3 ] - Modeling of heat generations for different tool profiles in friction stir welding: study of tool geometry and contact conditions

In this work, improved heat generation models are developed for straight and tapered shoulder geometries with different tool pin profiles in friction stir welding. The models are developed considering the welding process as a combination of the pure sliding and the pure sticking conditions. From the results, the amount of heat generation is directly proportional to the number of edges in the pi...
