Although highly effective, the cost and challenges of full-scale burst tests make their widespread use in pipeline projects impractical. However, sometimes burst tests are the only means to validate designs outside the envelope of applicability of the Battelle-Two Curve Method.  This research seeks to build upon the insights from the CO2Safe-Arrest JIP project by applying failure locus-based fracture models to predict running ductile fractures in gas pipelines.

Five fracture models were evaluated. The models were calibrated using three types of lab-scale tests: flat bar tensile tests, pure shear tests, and punch tests. A novel calibration approach using digital image correlation measurement was developed to eliminate the need for finite element analysis simulations.
