| Abstract: | The following case study outlines metallurgical, finite element, and fracture mechanics analyses conducted to determine the
cause of a pipeline rupture that resulted from prior external damage. Metallurgical and fractographic analyses indicated that
the rupture initiated from a shear crack caused by mechanical damage, and that the fracture mode was overload; no indication
of progressive growth was observed. Stress and fracture mechanics analysis indicated that the pipe ruptured at a pressure
below the maximum allowable operating pressure.
