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 ... -
Determination of Ductile Fracture Parameters of a Dual-Phase Steel by Optical Measurements
Gruben, Gaute; Vysochinskiy, Dmitry; Coudert, Térence; Reyes, Aase Gavina Roberg; Lademo, Odd-Geir (Peer reviewed; Journal article, 2013)Marciniak–Kuczynski and Nakajima tests of the dual-phase steel Docol 600DL (www.ssab.com/) have been carried out for a range of stress-states spanning from uniaxial tension to equi-biaxial tension. The deformation histories ... -
Ductile Fracture of Steel Sheets under Dynamic Membrane Loading
Gruben, Gaute; Morin, David; Langseth, Magnus; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2017)Failure prediction assessment is conducted based on validated finite element simulations of impact tests performed on 1.8 mm dual-phase and 1.0 mm martensitic steel sheets. The sheets were clamped between two steel rings ... -
Low-velocity impact behaviour and failure of stiffened steel plates
Gruben, Gaute; Sølvernes, S; Berstad, Torodd; Morin, David; Hopperstad, Odd Sture; Langseth, Magnus (Peer reviewed; Journal article, 2017)The behaviour and failure of stiffened steel plates subjected to transverse loading by an indenter is studied in this paper. Low-velocity dynamic and quasi-static tests of stiffened plates with geometry adopted from a ... -
Strain localization and ductile fracture in advanced high-strength steel sheets
Gruben, Gaute; Morin, David; Langseth, Magnus; Hopperstad, Odd Sture (Peer reviewed; Journal article, 2017)An experimental-numerical approach is applied to determine the strain localization and ductile fracture of high-strength dual-phase and martensitic steel sheet materials. To this end, four different quasi-static material ... -
Thermo-mechanical tensile testing of geothermal casing materials
Gruben, Gaute; Dillingh, Bert; Kaldal, Gunnar Skulason; Hoang, Nguyen-Hieu; Wollenweber, Jens; Rørvik, Gisle; Thorbjornsson, Ingólfur Ö; Nyhus, Bård (Peer reviewed; Journal article, 2021)Ultra-high temperature geothermal wells (>450 °C) have a large potential for increased energy yield as compared to conventional high-temperature geothermal wells (200-300 °C), but several research challenges must be resolved ...
