Influence of Internal Pressure on the Impact Behavior of Steel Pipelines

摘要: This article presents some experimental data recorded from 54 impact tests on pressurized mild steel pipes. The pipes were fully clamped across a span which was ten times the outside pipe diameter of 60 mm. had wall thickness 1.70 mm and impacted laterally by rigid wedge indenter at mid-span one-quarter-span positions. velocities ranged up to 13.6 m/s caused large inelastic indentations for lower values higher loss integrity could occur underneath and/or an end support. critical two failure energies obtained range internal gas pressures.
