    • Oxygen permeation and creep behavior of Ca1-xSrxTi0.6Fe0.15Mn0.25O3-δ (x=0, 0.5) membrane materials 

      Polfus, Jonathan M.; Xing, Wen; Pecanac, Goran; Fossdal, Anita; Hanetho, Sidsel Meli; Larring, Yngve; Malzbender, Jürgen; Fontaine, Marie-Laure; Bredesen, Rune (Peer reviewed; Journal article, 2016)
      Oxygen permeation measurements were performed on dense symmetric samples of Ca0.5Sr0.5Ti0.6Fe0.15Mn0.25O3−δ and compared to CaTi0.6Fe0.15Mn0.25O3−δ in order to assess the influence of the perovskite lattice volume on oxygen ...

    • Subsea power cable sheathing: an investigation of lead fatigue performance 

      Viespoli, Luigi Mario; Johanson, Audun; Alvaro, Antonio; Nyhus, Bård; Berto, Filippo (Peer reviewed; Journal article, 2020)
      The protection of subsea power cables against electrical failure is achieved by the use of a watertight layer. Due to its properties of chemical stability and ductility, lead has been the material of choice for this purpose ...

    • Tensile and fatigue behavior of a Pb-Sn-Sb alloy investigated via small-scale in-situ mechanical testing in SEM 

      Wan, Di; Viespoli, Luigi Mario; Johanson, Audun; Hagen, Anette Brocks; Berto, Filippo; Alvaro, Antonio (Journal article; Peer reviewed, 2020)
      Pb-Sn-Sb alloys (E-alloy) are commonly used in subsea power cable sheathing. Due to the relatively low melting temperature, i.e. around 600 K, this type of alloy is prone to experience microstructural time-dependent evolution ...

    • Time-dependent closure of a borehole in a viscoplastic rock 

      Xie, Xiyang; Fjær, Erling; Detournay, Emmanuel (Peer reviewed; Journal article, 2019)
      The paper describes a model to predict and analyze the time-dependent closure of a borehole drilled in a soft rock subjected to an initial isotropic stress, and the build-up of stress on a rigid casing after contact with ...
