• 3D motion dynamics of axisymmetric bodies falling through water 

      Alsos, Hagbart Skage; Faltinsen, Odd Magnus (Journal article; Peer reviewed, 2018)
      A new simplified method for analysis of 3D motion dynamics of axisymmetric slender bodies falling from air through water is presented. Slender-body theory for potential flow of incompressible water is combined with 2D + t ...
    • Effect of wave inhomogeneity on fatigue damage of mooring lines of a side-anchored floating bridge 

      Dai, Jian; Leira, Bernt Johan; Moan, Torgeir; Alsos, Hagbart Skage (Peer reviewed; Journal article, 2020)
      Mooring systems are important structural components of very long floating bridges. They effectively limit the transverse motions of the bridge under environmental loads. They also add viscous hydrodynamic damping to the ...
    • Evaluation of Nonlinear Material Behavior for Offshore Structures Subjected to Accidental Actions 

      Amdahl, Jørgen; Storheim, Martin; Alsos, Hagbart Skage (Journal article; Peer reviewed, 2018)
      Evaluation of the nonlinear structural response of any structure is a challenging task; a range of input parameters are needed, most of which has significant statistical variability and the evaluations require a high degree ...
    • Hydroplastic response of a square plate due to impact on calm water 

      Abrahamsen, Bjørn Christian; Alsos, Hagbart Skage; Aune, Vegard; Fagerholt, Egil; Faltinsen, Odd Magnus; Hellan, Øyvind (Peer reviewed; Journal article, 2020)
      This paper investigates large, plastic deflections of a square plate due to impact on calm water. Most research in the area has examined linear elastic structural responses to such impact, but hydrodynamic responses during ...
    • Ship Grounding: Analysis of Ductile Fracture, Bottom Damage and Hull Girder Response 

      Alsos, Hagbart Skage (Doktoravhandlinger ved NTNU, 1503-8181; 2008:250, Doctoral thesis, 2008)
      The present work is concerned with problems related to grounding of ships. This ranges from prediction of fracture to analysis of hull girder loads during grounding. The thesis is composed as a collection of articles and ...
