    • ATLAS of yield surfaces for strongly textured FCC polycrystals 

      Dumoulin, Stephane; Coudert, Térence; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2019)
      Discrete yield surfaces for several generic texture components, including randomness, found in aluminium alloys have been generated and used to calibrate the yield function Yld2004-18p. It is generally observed that the ...

    • 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 ...

    • Determination of forming limit strains using Marciniak-Kuczynski tests and automated digital image correlation procedures 

      Vysochinskiy, Dmitry; Coudert, Térence; Reyes, Aase Gavina Roberg; Lademo, Odd-Geir (Journal article; Peer reviewed, 2012)
      Forming limit strains are used to construct a forming limit diagram (FLD), which is a diagram in the principal strain space, traditionally used for designing forming operations of sheet metals. A line indicating the boundary ...

    • Experimental detection of forming limit strains on samples with multiple local necks 

      Vysochinskiy, Dmitry; Coudert, Térence; Hopperstad, Odd Sture; Lademo, Odd-Geir; Reyes, Aase Gavina Roberg (Journal article; Peer reviewed, 2016)
      Sheet metal formability is traditionally described by the forming limit curve (FLC). Experimental FLCs are obtained by performing formability tests and determining failure strains. The strains are usually measured either ...

    • Experimental detection of the onset of local necking in an aluminium sheet 

      Vysochinskiy, Dmitry; Coudert, Térence; Hopperstad, Odd Sture; Lademo, Odd-Geir; Reyes, Aase Gavina Roberg (Journal article; Peer reviewed, 2014)
      Forming limit diagrams (FLDs) are widely used to assess metal sheet formability. Experimental FLDs are obtained by performing formability tests and determining failure strains. The standard method for detection of forming ...

    • Experimental study on the formability of AA6016 sheets pre-strained by rolling 

      Vysochinskiy, Dmitry; Coudert, Térence; Hopperstad, Odd Sture; Lademo, Odd-Geir; Reyes, Aase Gavina Roberg (Journal article; Peer reviewed, 2017)
      The effects of prestrain by rolling on the formability of AA6016 sheets in the biaxial stretching region are studied in this paper. An experimental program including formability experiments has been carried out for as-received ...
