• 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 (Journal article; Peer reviewed, 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 in Dual-Phase Steel: Theoretical, Experimental and Numerical Study 

      Gruben, Gaute (Doktoravhandlinger ved NTNU, 1503-8181; 2012:257, Doctoral thesis, 2012)
      The thesis is focused on quasi-static ductile fracture in the low range of stress triaxiality of the dual-phase steel Docol 600DL. The study includes mechanical testing, theoretical aspects of ductile fracture and numerical ...
    • Ductile Fracture of Steel Sheets under Dynamic Membrane Loading 

      Gruben, Gaute; Morin, David; Langseth, Magnus; Hopperstad, Odd Sture (Journal article; Peer reviewed, 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 ...
    • Heat-Treatable Aluminum Alloys: Three-Point Bending 

      Westermann, Ida; Gruben, Gaute (Chapter, 2018)
    • Low-velocity impact behaviour and failure of stiffened steel plates 

      Gruben, Gaute; Sølvernes, S; Berstad, Torodd; Morin, David; Hopperstad, Odd Sture; Langseth, Magnus (Journal article; Peer reviewed, 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 ...
    • Low-velocity impact on high-strength steel sheets: An experimental and numerical study 

      Gruben, Gaute; Langseth, Magnus; Fagerholt, Egil; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2016)
      Low-velocity impact tests were performed on dual-phase and martensitic steel sheets and compared with corresponding quasi-static tests. The geometry and loading condition of the specimens were similar to formability tests, ...
    • Modelling of Ductile Fracture in Steel Structures 

      Eriksen, Kristoffer Frøyd (Master thesis, 2021)
      Rørledninger som befinner seg til havs og transporterer CO2 er sårbare for løpende duktile brudd, som potensielt kan føre til betydelige kostnader og tap av menneskeliv. Dersom rørledningene er riktig dimensjonert, kan ...
    • Simulation of ductile crack propagation in dual-phase steel 

      Gruben, Gaute; Hopperstad, Odd Sture; Børvik, Tore (Journal article; Peer reviewed, 2013)
      The modified Mohr–Coulomb and the extended Cockcroft–Latham fracture criteria are used in explicit finite-element (FE) simulations of ductile crack propagation in a dual-phase steel sheet. The sheet is discretized using ...
    • Strain localization and ductile fracture in advanced high-strength steel sheets 

      Gruben, Gaute; Morin, David; Langseth, Magnus; Hopperstad, Odd Sture (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 ...
