Title

Numerical modeling of a material-flow and fatigue in friction stir processing

Abstract

"The present study involves fatigue like analysis of partially friction stir processed components and numerical modeling of material flow during friction stir processing. Finite element based fatigue life calculations were carried out for various A356 samples and components including an automotive wheel rim in cast and partially friction stir processed conditions. The visco-plastic flow of material around the pin is simulated by solving the equations of conservation of mass, momentum and energy. The forces acting on the tool are estimated for various welding speeds and rotational velocities of the tool"--Abstract, page iv.
