Residual stresses can have a significant impact on the stability of structural members. In the case of I-section beam elements, such stresses can impact lateral--torsional buckling (LTB) capacity, particularly in the inelastic range. I-sections are typically fabricated by either rolling as a...

This thesis presents a thorough examination of the corrosion and fouling behaviour of crude oil at refining conditions on industrially applicable heat transfer surfaces. The depletion of light sweet crude oil reserves means that the processing of ever heavier and more sour crude oils is...

Stainless steel is one of the most commonly used materials in most industries. Excellent corrosion resistance of stainless steel is due to the formation of an oxide film on the surface (passive film), which protects the material from continuous corrosion attacks. When subjected to an attack...

An evaluation of the resistance of two different X70 pipeline steels to hydrogen-induced cracking in severe (pH 2.7 and 1 atm H2S) and intermediate (pH 5.5 and 1 atm H2S) sour service conditions was undertaken. The two steels used in this work, X70-X and X70-B, were selected based on their...

Seismic velocity dispersion in crystalline rock is investigated through experimental measurements on two natural quartzite specimens. The quartzites are thermally damaged to induce low aspect ratio cracks and the shear and Young’s moduli are measured across a range of effective pressures, from...

Reliability Centered Maintenance (RCM) and Ultrasonic Leakage Detection (ULD) as a maintenance and condition monitoring technique for freight rail airbrakes in cold weather conditions
DownloadSpring 2015
Freight rail airbrakes need improvement in reliability to reduce failures, which can lead to harm to the environment, loss of human life, and a negative impact on the economy. This research focuses on identifying the failures of airbrakes using a Reliability Centered Maintenance (RCM) framework,...

The Role of Sulfur Species in Establishing the Corrosion Reactions in Refinery Metallurgies
DownloadSpring 2016
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...

Ultrasonic Characterization of Bitumen with Pressure and Temperature: Implications for seismic monitoring of the Grosmont Formation
DownloadFall 2018
The vastly untapped carbonate Grosmont Formation in north-eastern Alberta may hold in excess of a couple of hundred billion barrels initial volume of bitumen in place. Bitumen, an ultra-heavy hydrocarbon oil, possesses a density comparable to water, but a dynamic shear viscosity million times...

Traditionally in pipeline steels and welds, ultrasonic testing (UT) has been used for crack and/or flaw detection. The work presented in this Thesis explores the use of this technique to characterize the microstructure of pipe steels. Ultrasonic velocity calculations, for shear and longitudinal...
