... was conducted to demonstrate the compressive strain limit. The numerical analysis based on laser measurement, reverse engineering and finite element method was also performed to investigate the pipe buckling behavior. The results of full-scale test imply that finite element method can predict buckling strain...

... ABSTRACT: The longitudinal compressive strain associated with the onset of pipelines buckling is widely used in strain-based design as the critical buckling strain (CBS). Available pipeline codes, standards and recommended design criteria in literatures define the CBS as a function of pipe's...
