A Systematic Methodology to Develop Scaling Laws for Thermal Features of Temperature Field Induced by a Moving Heat Source
DownloadSpring 2021
A systematic methodology is developed to formulate scaling laws in closed-form for thermal features of moving line heat source and Gaussian heat source problems, with wide generality, high accuracy and practical simplicity, from fundamental principles. The expressions are written in form of a...

20Cr-32Ni-1Nb stainless steel alloys are commonly used in hydrogen reformer manifolds for transporting hot hydrogen by-products at 750-950 celcius. After long periods of exposure, embrittling secondary carbides and intermetallic phases can precipitate at the grain boundaries which can drastically...

Experimental studies and asymptotic scaling for the development of engineering tools to predict coupled heat transfer and plastic deformation in Friction Stir Welding (FSW)
DownloadFall 2016
A study of temperature, force, and torque was performed using a set of ten different friction stir welding (FSW) tools. It was observed that pin diameter had the most significant effect on steady state welding temperature followed by shoulder diameter having a smaller but measureable effect. Pin...

Full-Scale Testing of the Fatigue Life of Laser Additive Manufacturing Repaired Alloy Steel Components
DownloadFall 2017
Laser additive manufacturing, or laser cladding, is a weld overlay technique that is being increasingly used for hardfacing and corrosion resistant overlays and dimensional repairs of oil and gas, petrochemical, and mining components. However, laser cladding's use in industry is currently limited...

In submerged arc welding (SAW), the welding takes place under a flux bed. The physical phenomena taking place under the flux bed is crucial in determining the quality of the final weld. The presence of the flux layer prevents the direct visibility of the weld zone during welding; this limitation...

The weld bead width and the penetration depth are major parameters that determine the mechanical strength of the weld joint. The analytic models, such as the Gaussian heat source model, may provide quite accurate estimations for the weld width and penetration; however, the model does not account...
