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...
