Fall 2022
A study of the kinetic and microstructural aspects of austenite formation in low carbon pipeline steels during continuous heating and a model capable to predict the interface velocity are presented in this study. The overall goal of this work is to increase the level of understanding concerning...

Effect of unloading rate on surface crack growth during underload cycles in X-65 pipeline steel exposed to near-neutral pH environments
DownloadSpring 2019
This thesis has studied the crack growth behaviour of fully-coated, partially-coated, and fully-exposed semi-elliptical cracks immersed in a near-neutral pH environment with an applied cathodic potential. The effects of adding a one-hour monotonic hold and waveform shape were explored. The...

Prairie plant species at risk in Southern Alberta: identification of critical habitat at the microsite level for Halimolobos virgata (Nutt.) O.E. Schulz and determination of set back distance between pipeline disturbance and Halimolobos virgata and Cryptantha minima Rydb.
DownloadFall 2011
Little is known about the effect disturbances such as pipelines can have on prairie plant species at risk and their critical habitat in Alberta. Halimolobos virgata appears to be a ruderal, disturbance evolved species that occupies a unique rim niche. This habitat around the rim of depressional...

Predictive Method for Pipeline Strain Demand Subject to Permanent Ground Displacements with Internal Pressure & Temperature
DownloadFall 2022
Pipelines subject to ground deformations generated by geohazard loads carry high importance on pipeline analysis, design, and assessment due to risk of structural damage or failure. Additionally, internal pressure and temperature variation within an operating pipe induce additional strains in...

Stress- and strain-based reliability assessment of pipelines subjected to internal pressure and permanent ground movement
DownloadFall 2023
As a critical member of infrastructural lifeline, pipelines fulfill a vital role in energy delivery across long distances from source to market. Pipelines at service can be exposed to a wide variety of loads depending on the environment and the area of application. Internal pressure and ground...
