Buckling Behavior of Buried High Strength Steel Pipeline Critical Buckling Strain in High Strength Steel Pipes

Active fault is the most dangerous natural hazards of buried steel pipelines, as large stress and strain induced by ground movement can lead to pipe failure, which may cause severe accidents. Based on nonlinear finite element method, local buckling behavior of buried high strength X80 steel pipelines under compression strike-slip fault was Critical Buckling Strain in High Strength Steel Pipes Effect of Material Stress-Strain Behavior and Pipe Critical Buckling Strain in High Strength Steel Pipes Then, a finite-element analysis method for evaluating the deformability of the line pipe was established. By using this method, parametric studies were carried out. The effects of the strain-hardening behavior and pipe geometry on the deformability of the high-grade pipelines were examined.

Effects of Material Anisotropy on the Buckling Resistance Critical Buckling Strain in High Strength Steel Pipes

This research investigates the buckling response of high strength steel (HSS) pipes with anisotropic material properties. The stress-strain responses of eight material types of grades X80 and X100 pipes were studied focusing on the elastic, yielding, and early plastic regions that affect the pipes buckling.

Post-Buckling Failure Modes of X65 Steel Pipe An Critical Buckling Strain in High Strength Steel Pipes

These bending loads can induce large longitudinal strains, which may trigger local buckling on the pipe's compressive side and/or lead to rupture of the pipe's tensile side. In this article, the post-buckling failure modes of pressurized X65 steel pipelines under monotonic bending loading conditions are studied via both experimental and Critical Buckling Strain in High Strength Steel Pipes STRAIN HARDENING EFFECT ON CRITICAL STRAIN conditions, which could induce deformation and strain or even lead to pipe failure, the critical value of strain for a bending pipe at buckling might be rationally taken as a parameter in pipeline design in nowadays . However, the assessment of critical buckling strain is - still on the way, though some formulae have been proposed .
