Strain model and experimental study of elastic viscoplastic for crack-tip zone of X80 steel pipe
The mechanical state of the process zone at the crack-tip is one of the main factors that affect crack initiation and growth in the long-term safe operation of oil and gas pipelines. Many tests showed that the stress and strain fields in the fracture-tip process zone can be used to define the crack...
