Strains and strain rates during friction stir welding

Strains experienced by materials during friction stir welding (FSW) are important but scarce in the literature. Here we report the computed strains and strain rates during FSW of AA2524 from a three-dimensional coupled viscoplastic flow and heat …

Advances and Promises of Weld Pool Convective Heat Transfer Calculations

Investigations of heat transfer and fluid flow in the weld pool have become increasingly more realistic and useful in recent years because of advances in computational hardware and software. The goal of this paper is to provide an outline of the …

Torque, Power Requirement and Stir Zone Geometry in Friction Stir Welding through Modeling and Experiments

The torque, power requirement and stir zone geometry during friction stir welding of AA2524 aluminum alloy were modeled by solving the equations of conservation of mass, momentum and energy. The model predictions agreed well with the corresponding …
