This decommissioned ERA site remains active temporarily to support our final migration steps to https://ualberta.scholaris.ca, ERA's new home. All new collections and items, including Spring 2025 theses, are at that site. For assistance, please contact erahelp@ualberta.ca.
Theses and Dissertations
This collection contains theses and dissertations of graduate students of the University of Alberta. The collection contains a very large number of theses electronically available that were granted from 1947 to 2009, 90% of theses granted from 2009-2014, and 100% of theses granted from April 2014 to the present (as long as the theses are not under temporary embargo by agreement with the Faculty of Graduate and Postdoctoral Studies). IMPORTANT NOTE: To conduct a comprehensive search of all UofA theses granted and in University of Alberta Libraries collections, search the library catalogue at www.library.ualberta.ca - you may search by Author, Title, Keyword, or search by Department.
To retrieve all theses and dissertations associated with a specific department from the library catalogue, choose 'Advanced' and keyword search "university of alberta dept of english" OR "university of alberta department of english" (for example). Past graduates who wish to have their thesis or dissertation added to this collection can contact us at erahelp@ualberta.ca.

A further look at Archard’s Equation to extract additional information from the material loss ~ load curve
DownloadFall 2018
Rahman, Abu Hasnat Mohammad Azadur
Archard’s wear equation has been widely used in industry for preliminary selection of materials mainly based on hardness. According to Archard’s equation, the material wear rate is linearly proportional to the normal force. However, the wear rate or material volume loss per unit sliding distance...

A molecular dynamics modeling study on the mechanical behavior of nano-twinned Cu and relevant issues
DownloadFall 2010
As a candidate for dynamic electric contacts, Nano-twinned copper has intrinsic conductivity and enhanced fretting resistance. To better understand its general mechanical behavior, we conduct molecular dynamics simulation studies to investigate responses of nano-twinned copper to stress and to...

Comprehensive study of the abrasive wear and slurry erosion behavior of an expanded system of high chromium cast iron and microstructural modification for enhanced wear resistance
DownloadSpring 2014
High chromium cast irons (HCCIs) have been demonstrated to be an effective material for a wide range of applications in aggressive environments, where resistances to abrasion, erosion and erosion-corrosion are required. For instance, machinery and facilities used in mining and extraction in...

Fall 2017
High Chromium Cast Irons (HCCIs) are widely used in mineral processing, slurry pumping and manufacturing processes, where high resistance to erosion and synergetic erosion-corrosion is required. The excellent performance of HCCIs results from their microstructure, which consists of hard carbides...

Dependence of the Interfacial Adhesion between Two Different Types of Material on their Electron Work Function and Electrical Conductivity
DownloadFall 2021
We observed and investigated a novel interfacial phenomenon related to the dependence of interfacial bonding or adhesive force (Fad) between two substances on the difference in their Electron Work Functions (EWF) or Δφ, and developed a model to quantify such a dependence. First, using...

Fall 2015
Mechanical, tribological and corrosion properties of metallic materials are of significance to their industrial applications and have been studied for long time. Efforts are continuously made to correlate these properties to more fundamental parameters in order to effectively improve the...

Development of effective green lubricants for industrial drilling systems in aggressive environments
DownloadSpring 2024
In drilling systems used in the oil and gas industry, drilling equipment often encounters critical problems which could result in irreparable damage to metallic equipment. Chemical and physical interactions at the contact between different parts, such as drill bits, drill strings with well walls...

Effects of Mo and B additives on hardness and the resistance of Cu-Ni alloy to wear, corrosion and corrosive wear
DownloadSpring 2020
Due to its corrosion resistance, conductivity, and modifiable mechanical properties, CuNi alloy has found a wide range of applications, especially in the marine environment. It is highly desired if the mechanical strength and wear resistance of CuNi alloy can reach a level comparable to that of...

Spring 2022
Although it is known that strain-hardening helps improve the wear resistance of metallic materials, puzzles or inconsistent phenomena still exist regarding the effect of strain-hardening on the wear resistance of metallic materials. It was reported that strain-hardening showed little or limited...

Fall 2009
In this work, a general dynamic model was proposed to simulate the dynamic motion of microtubules driven by dynein motors, which is of importance to the design of potential nano-bio machines composed of dynein motors and microtubules. The model was developed based on Newton's law of motion. By...
