Abstract

In order to evaluate the crack arrestability of line pipes to the propagating shear fracture, the partialgas burst test was carried out on many line pipes of varied notch ductility, sizes and test conditions. A method to estimate the fracture energy of test pipes was established and the required notch ductility to line pipes against the propagating shear fracture of actual pipelines was introduced.
