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, ... -
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 ...
