Abstract
The strain capacity of pipelines is one of the primary factors for the design of those made of high-strength and hightoughness steel. The work presented in this paper describes the evaluation method for the compressive-bending plastic buckling capacity of pipeline steel tube based on strain-based design. The evaluation method developed in this paper used Gurson-Tvergaard -Needleman(GTN) model which is the constitutive model of the steel by user-material subroutine (UMAT) for the commercial software of ABAQUS. The model parameters were decided by comparison between experiment and simulated data. The compressive-bending experimental results are simulated using this evaluation method by means of the maximum bending moment as well as the critical compressive strain. Using this method, we simulated compressive-bending plastic buckling behavior of pipeline steel tube for the practical design in the hazardous region.
