• A numerical study of beam-to-column joints subjected to impact 

      Grimsmo, Erik Løhre; Clausen, Arild Holm; Aalberg, Arne; Langseth, Magnus (Journal article; Peer reviewed, 2016)
      Limited documentation is concerned with the behaviour of steel joints subjected to severe impulsive loading originating from incidents such as explosions or impact. In this paper, finite element simulations are used to ...
    • An experimental study of static and dynamic behaviour of bolted end-plate joints of steel 

      Grimsmo, Erik Løhre; Clausen, Arild Holm; Langseth, Magnus; Aalberg, Arne (Journal article; Peer reviewed, 2015)
      Many actions, such as accidental or malicious explosions, may impose high loading rates to structural frames. To enhance the knowledge of the behaviour of joints subjected to severe impulsive loading, a double-sided ...
    • Behaviour of steel connections under quasi-static and impact loading An experimental and numerical study 

      Grimsmo, Erik Løhre (Doctoral theses at NTNU;2017:159, Doctoral thesis, 2017)
      This PhD thesis is concerned with the behaviour of steel joints and connections subjected to quasi-static and impact loading. A major part of the work involves experimental testing, which includes both component and ...
    • Failure modes of bolt and nut assemblies under tensile loading 

      Grimsmo, Erik Løhre; Aalberg, Arne; Langseth, Magnus; Clausen, Arild Holm (Journal article; Peer reviewed, 2016)
      Thread failure of bolt and nut assemblies subjected to tension is generally undesired because it is a less ductile failure mode than fracture of the threaded shank of the bolt (denoted bolt fracture). Another issue is that ...
    • FEM Simluations of Shear Waves in the Heart Wall 

      Grimsmo, Erik Løhre (Master thesis, 2013)
      With knowledge of the stiffness of the heart wall, medical personnel can diagnose patients' heart condition. The stiffness of the heart can be altered, e.g. due to a heart attack. New ultrasound technology allows for in ...
    • How placement of nut determines failure mode of bolt-and-nut assemblies 

      Grimsmo, Erik Løhre; Aalberg, Arne; Langseth, Magnus; Clausen, Arild Holm (Journal article; Peer reviewed, 2017)
      Bolt-and-nut assemblies under tension loading can either fail by bolt fracture or thread failure. The latter failure mode is arguably undesirable because it leads to failure at a comparatively low deformation level. Moreover, ...
    • Numerical study of fillet welds subjected to quasi-static and impact loading 

      Grimsmo, Erik Løhre; Dæhli, Lars Edvard; Hopperstad, Odd Sture; Aalberg, Arne; Langseth, Magnus; Clausen, Arild Holm (Journal article; Peer reviewed, 2017)
      Fillet welding is widely used in connections in civil engineering and marine structures. Thus, understanding the behavior of fillet welds under various types of loading is important, and numerical simulations can provide ...
    • Quasi-static and dynamic behaviour of fillet welded connections 

      Paus, Martin Flottorp (Master thesis, 2016)
      Introduction Understanding the behaviour of the joints in a construction is crucial for structural engineers. In fact, the behaviour of steel joints exposed to static loading is well documented. Steel joints exposed to ...
