      Zhao, Kai; He, Jianying; Ringdalen, Inga Gudem; Zhang, Zhiliang (Peer reviewed; Journal article, 2018)
      A thermodynamic model is derived to study the void nucleation in ideal lattices under hydrostatic tension loading and predicts that the plasticity has to be initiated before homogeneous nucleation of voids. Molecular ...
    • Effect of low temperature tensile properties on crack driving force for Arctic applications 

      Dahl, Bjørn Augdal; Ren, Xiaobo; Akselsen, Odd Magne; Nyhus, Bård; Zhang, Zhiliang (Peer reviewed; Journal article, 2017)
      Many petroleum companies expand their activities further north towards the Arctic region, resulting in design temperatures down to −60 °C, which is much lower than what is usual for most current petroleum installations. ...

      Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)
      In this study, the effect of Lüders plateau on the ductile crack growth resistance has been investigated with the Gurson damage model and the modified boundary layer (MBL) model, under mode I plane strain condition. The ...
    • Effect of Thermal Residual Stresses on Ductile-to-Brittle Transition of a Bi-material Specimen by Using the CAFE Method 

      Li, Yang; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)
      The effect of residual stress on fracture of materials or structures has been widely studied. However, its influence on ductile-to-brittle transition (DBT), a crucial phenomenon of structural materials, has rarely been ...
    • Efficient Liquefaction of Carbon Dioxide on Superlyophobic Surfaces 

      Snustad, Ingrid; Ervik, Åsmund; Austegard, Anders; Reigstad, Gunhild Allard; He, Jianying; Zhang, Zhiliang; Brunsvold, Amy (Journal article, 2019)
    • Experimental measurement of temperature-dependent equivalent stress-strain curves of a 420 MPa structural steel with axisymmetric notched tensile specimens 

      Tu, Shengwen; Ren, Xiaobo; He, Jianying; Zhang, Zhiliang (Peer reviewed; Journal article, 2019)
      Recently, the authors in this paper proposed a correction function to determine material’s equivalent stress-strain curve with axisymmetric-notched tensile specimens. In this study, tensile tests were performed at room ...
    • A framework for classification of snow- and icephobicity 

      Borrebæk, Per-Olof; Rønneberg, Sigrid; Jelle, Bjørn Petter; Klein-Paste, Alex; Zhang, Zhiliang; He, Jianying (Peer reviewed; Journal article, 2020)
      For decades, there has been no proper thermodynamic definition of icephobicity. Some claim icephobic properties at an adhesion lower than 100 kPa, whereas others claim it when the accretion of ice is significantly prolonged. ...
