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 ...
