When axial fast ductile fracture occurs in high-pressure gas pipes, the plane of the crack opening does not necessarily remain parallel to the pipe axis. There is in general a tilt angle between the opening flanks and the pipe axis. The present discussion shows that taking into account the presence of a tilt angle results in larger estimates of surface CTOA than those reported in a recent paper (Shibanuma et al., 2018). Considering the effect of tilt angle, the data reported in Shibanuma et al. (2018) support the transferability of CTOA from DWTT-type specimens to full-scale pipe.
