A novel fracture calibration method is presented for material models applied in finite element analysis of pipeline steels exposed to running ductile fracture. The calibration is based on the drop-weight tear test which is commonly applied for qualification of pipeline steels. The method is applied...

In this study, we present results from a numerical model of a full-scale fracture propagation test where the pipe sections are filled with impure, dense liquid-phase carbon dioxide. All the pipe sections had a 24″ outer diameter and a diameter/thickness ratio of ∼32. A near symmetric telescopic set...

This work considers a predictive numerical modelling approach for fracture-propagation control in CO₂-transport pipelines, an area where current engineering tools do not work. Fluid-structure interaction model simulations are compared with three published medium-scale crack-arrest experiments with...
