Spring 2013
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...
