Stress-Assisted Pitting Corrosion Studies in Metallic Structures Using Advanced Modeling Methodologies
Pitting corrosion poses a significant threat to deepwater oil and gas production facilities, yet our current understanding of its impact on specific systems such as steel catenary riser (SCR), tensioned leg platforms (TLP), ...
Experimental and numerical study of mechanics and mechanisms of mode I fracture of a textured magnesium alloy
In recent years, magnesium alloys have gained increasing application in the automotive industry to achieve weight reduction in vehicle components which is crucial for enhancing fuel efficiency and meeting stringent emission ...
Robust Numerical Modeling of Adhesively-Bonded Joints for Safety Assessment of Vehicle Body Structures Subjected to Extreme Loading
Continuous adhesively-bonded joints can lead to stiffer vehicle body structures in contrast to conventional spot-welded steel sheet metal-based unitized vehicle body design. For a given target stiffness, adhesive bonding, ...
Low Head Hydraulic Pumping – Design, Simulation, and Field Validation of Ram and Turbine Pump in Indian River Basin
Water energy is essential for economic expansion and human development. Social progress
and economic growth depend on meeting water energy needs sustainably. The use of non renewable energy sources for pumping water to ...
A Multiscale Study of the Thermodynamics and Kinetics of Vacancy–grain-boundary Interactions
Grain boundaries (GBs) influence many physical and mechanical properties of crystalline materials. This is primarily because of their interactions with other kinds of defects, such as point and line defects. Such interactions ...
Experimental and Theoretical Insights into Impact Phenomena of Small Scale Liquid Interfacial Systems
This work explores impact phenomena experimentally and theoretically for various
interfacial systems ranging from medical diagnostics to drop impacts on solids and
immiscible liquids. We study a hitherto unexplored impact ...
Experimental investigation of syngas combustion using a novel two-stage combustor
In recent years, syngas has gained research interest as the focus shifts from fossil to renewable fuels. Syngas generated from biomass such as wood, agricultural residue, and paper is a promising fuel to achieve net-zero ...
Identification of crystalline structures of clathrate hydrates during molecular simulations using machine learning
Molecular simulation is a powerful tool that links a system’s microscopic behaviour to its macroscopic observable features. The data obtained from a molecular simulation act as a digital microscope, i.e., it contains ...
Bayesian implicit filters for the analysis of numerically stiff structural dynamic state space models
This thesis reports on combined experimental and computational investigations conducted on problems of state and combined state and parameter estimation applied to vibrating engineering structures. The standard dynamic ...
Effect of High Pressure Torsion Processing on Precipitate Containing Alloys
Severe plastic deformation (SPD) processes yield excellent grain refinement in metallic materials by application of very large shear strains while retaining the initial sample dimensions. Its effects on simultaneously ...
