Abstract

The strain capacity of tensile deformation of pipeline is evaluated by the strain-based design using standards and numerical methods in this study. We calculate the allowable tensile strain according to the given geometries and flaws of the pipeline by strain-based design rules given in DNV-OS-F101 and CSA-Z662. They are compared with the tensile strain capacity by classical crack band model using commercial software of ABAQUS. We propose the fracture toughness (crack tip opening displacement (CTOD))-crack growth-strain chart for evaluating the strain capacity for given fracture toughness. In addition, they are also compared with the chart by the recently developed extended finite element method (XFEM) which shows better resolution than classical crack band model.
