A Morphology-Based Analysis of Crack Initiation, Propagation and Arrest Behaviors in Pre-Defected CO2 Pipelines

Crack initiation, propagation and arrest in high-pressure CO2 pipelines are strongly affected by decompression behavior, defect geometry and material resistance. In this study, nine DN100-scale CO2 pipe burst tests with prefabricated axial defects were analyzed from a morphology-based perspective. Instead of evaluating...
