• 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, ...
    • Numerical study on the effect of the Lüders plateau on the ductile crack growth resistance of SENT specimens 

      Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Journal article, 2018)
      The increasing demand of energy prompts the petroleum industry exploitation activities to the Arctic region where the low temperature is a strong challenge, both for structural design and material selection. For structural ...
    • On the description of ductile fracture in metals by the strain localization theory 

      Morin, David; Hopperstad, Odd Sture; Benallal, Ahmed (Journal article; Peer reviewed, 2017)
      Numerical simulations based on the bifurcation and imperfection versions of the strain localization theory are used in this paper to predict the failure loci of metals and applied to an advanced high strength steel subjected ...
    • 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 ...
    • Supergiant elasticity and fracture of 3D spirally wound MoS2 

      Wu, Jianyang; He, Jianying; Ariza, Pilar; Ortiz, Michael; Zhang, Zhiliang (Peer reviewed; Journal article, 2020)
      Recently experimentally synthesized three-dimensional (3D) MoS2 spiral is a new kind of helical structure with technically robust properties. Among them, the mechanical properties of such appealing materials are indispensable ...
