Bond Performance between Lightweight Concrete with Crumb Rubber and Glass Fibre Reinforced Polymer Bar
DownloadFall 2017
For any reinforced concrete structure, the bond between concrete and the reinforcement bar is the most important parameter from structural standpoint. Notwithstanding numerous prior studies on describing this interaction for different reinforcing bars, not enough understanding exists for fibre...

The classical Battelle two-curve method is proved to be non-conservative in calculating the arrest fracture toughness of high grade line pipes. In this thesis, first, the concept of ―limit (crack) speed‖ is introduced to the existing two-curve method, which leads to a modified two-curve method...

Development of Non-Destructive Indentation Fracture Toughness Methodologies for High Strength Alloys Case study: High strength rail steels and aluminum
DownloadFall 2024
Rail derailment comprising largely from main track derailments frequently occur in the Canadian railway network. Reports have shown that some of these derailments experienced a train-initiated emergency brake application caused primarily from broken rails especially at extreme cold temperatures....

New Destructive and Non-Destructive Methods to Quantify Fracture Toughness of High-Strength Rail Steels
DownloadFall 2017
Rail breaks, resulting from increasing heavy axle-load operations and harsh environmental conditions, remain a major cause of catastrophic derailment of vehicles in North America. The objective of this research project is to develop convenient testing methods to identify the optimum high-strength...
