Sensitivity of plastic response of defective pipeline girth welds to the stress-strain behavior of base and weld metal
One of the key parameters influencing the acceptability of a pipeline girth weld defect subjected to remote plastic deformation is the strength mismatch between weld and base metal. However, no single definition exists for weld strength mismatch, as it can be defined either on the basis of yield str...
