“…It appears, on the basis of this limited study, that the general behaviour is similar whether or not a pipeline is pressurised with gas or water. In view of the observations of the study reported in Reference [8] and the discussion in section 1, it is clear that further work is required in order to clarify the influence of different contents on the impact behaviour of a pressurised pipeline. Table 2.…”

“…This localisation of the damaged area is due likely to the additional inertial resistance offered by the contents of a pipeline. Thus, the impact energy is absorbed in a smaller volume of the tube material which is responsible for a decrease in the perforation energy, as observed in References [4,[7][8][9][10]12]. Moreover, the experimental studies reported in References [4,[7][8][9][10]12] indicate that an increase in the internal pressure does not produce any important further change in the response, which, perhaps, suggests that the density of the contents is the most significant parameter.…”

“…Two horizontal hydraulic actuators apply the axial load N a , while a third bends the pipe transversely (three-point bending) using deformation control. As a pointed impactor perforates a pipe more easily [49], the sharpest geometry (nose radius 100 value of the applied axial load was based on simplified beam calculations, and is well below the elastic limit N el ≈ 718 kN estimated by…”
