Characterization of Modern High Toughness Steels for Fracture Propagation and Arrest Assessment- Phase II
The development of high toughness linepipe materials is reducing the relevance of current material test methods and their application to design. Current fracture mechanics models, plastic collapse schemes and test methods are inadequate to determine the crack arresting capacity of a particular steel alloy/linepipe component. Furthermore, relatively inexpensive tests that are quick to perform are simply not available to accurately assess the fracture behavior of today's high strength and high toughness linepipe steels.
