    • Influence of microstructure on work-hardening and ductile fracture of aluminium alloys 

      Pedersen, Ketill Olav; Westermann, Ida; Furu, Trond; Børvik, Tore; Hopperstad, Odd Sture (Journal article, 2015)
      The effect of microstructure on the work-hardening and ductile fracture of aluminium alloys was studied using an experimental–numerical approach. Four aluminium alloys with different strength and particle content were ...

    • Influence of pre-compression on the ductility of AA6xxx aluminium alloys 

      Frodal, Bjørn Håkon; Pedersen, Ketill Olav; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2017)
      Reversed loading experiments were conducted to study the influence of pre-compression on the ductility of three aluminium alloys. Diabolo-shaped specimens were machined from extruded profiles along the transverse direction, ...

    • Work-hardening and ductility of artificially aged AA6060 aluminium alloy 

      Westermann, Ida; Pedersen, Ketill Olav; Børvik, Tore; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2016)
      The work-hardening and ductility of an artificially aged AA6060 aluminium alloy were studied based on tensile tests of smooth and notched cylindrical samples. The alloy was tested after three processing steps, each followed ...
