A fracture-propagation-control model for pipelines transporting CO2-rich mixtures including a new method for material-model calibration
Nordhagen, Håkon Ottar; Munkejord, Svend Tollak; Hammer, Morten; Gruben, Gaute; Fourmeau, Marion; Dumoulin, Stephane (Journal article; Peer reviewed, 2017)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 ... -
Calibration of Pipeline Steel Model for Computational Running Ductile Fracture Assessment
Gruben, Gaute; Dumoulin, Stephane; Nordhagen, Håkon Ottar; Hammer, Morten; Munkejord, Svend Tollak (ISOPE - International Offshore and Polar Engineering Conference. Proceedings;29, Chapter; Peer reviewed, 2019)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 ...
