Spring 2017
Delayed coking is an essential technology in the upgrading of heavy hydrocarbons in the Canadian oil sands for producing saleable liquid and gas products in order to sustain a viable national energy industry. Delayed coking units contain among the largest pressure vessels used in heavy industry...

Investigation of Mechanical Properties, Porosity and Geometric Deviation of Lattice Structures Manufactured by Additive Manufacturing
DownloadSpring 2022
This thesis reports fabrication, mechanical characterization, finite element modeling, and geometric analysis of lattice structures. A net-shaped 316L stainless steel lattice structure composed of diamond unit cells was fabricated by selective laser melting (SLM). The cavities in the lattice...

Multiphysical dynamic fracture analysis of biomimetic composites based on non-Fourier heat conduction
DownloadFall 2023
In the world of engineering, strength and toughness are two highly desirable properties to materials design. Biological materials have already mastered both of these properties within the threads they protect themselves in harsh nature. The key to both the biomaterial’s ability to resist external...

Fall 2020
Classical thermoelastic analysis within the framework of classical elasticity and Fourier’s heat conduction cannot meet the increasing demand with the rapid development of new technologies and new materials. Fourier heat conduction theory indicates the speed of thermal propagation is infinite,...

Fall 2015
Hot rolled steels are steel alloys manufactured through a very efficient direct rolling process following solidification above the recrystallization temperature. Hot rolled steels have a unique microstructure with relatively high contents of bainite and martensite phases continuously dispersed in...

Optimal Design of Coke Drum Skirt Slots and Analysis of Alternative Skirt Support Structures for Thermal-Mechanical Cyclic Loading
DownloadFall 2017
The skirt-to-shell attachment weld on coke drums is susceptible to low-cycle fatigue failure due to severe thermal-mechanical cyclic stresses. Therefore, various skirt attachment designs have been proposed and implemented to reduce stress and thus improve reliability. The most common skirt design...
