Development of In-situ Fracture Toughness Evaluation for Bridge Safety

This research will develop and evaluate non-destructive test methods that have the potential for providing information about material resistance to fracture. This may include in-situ measurements of surface hardness, acoustic-emission measurements, and/or advanced ultrasonic evaluation. Test results obtained from these advanced technologies will be correlated with fracture toughness and absorbed impact energy for a variety of metallic materials used in highway infrastructure.
