摘要: Abstract Pipeline transport is one of the main solutions for oil and gas transmission distribution. The pipeline in service may be subjected to complicated loads (internal pressure, tension or compression, bending their combination) when crossing complex geohazard regions. In this study, compressive strain capacity pressurized pipelines under eccentric axial compression investigated numerically. Meanwhile, effects internal pipe diameter-to-wall-thickness ratio ( D / t ) material hardening on are studied. It has been found out that buckling behavior pipes depends capacity. increases with increase pressure capacity; while displays a negative effect.
