      This thesis is concerned with mooring line failure and 3D representations of corroded chain surfaces. Equipment for making such representations have been evaluated through a feasibility study carried out at NTNU. An ATOS ...
    • 5D Byggeprosess: Modellbasert prosjektstyring 

      Blom, Gustav (Master thesis, 2011)
      Sammenlignet med industrielle produksjonsprosesser sliter byggebransjen med sløsing av tid og ressurser som følge av dårlig kommunikasjon og lite eksplisitt prosjektstyring. Bruk av bygningsinformasjonsmodeller kan vurderes ...

      Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2016)
      This short note presents the updating of element thickness due to large membrane strains recently introduced in some shell elements (Q4GS and T3GS) of the EUROPLEXUS code (EPX).
    • A combined isotropic, kinematic and distortional hardening model for aluminum and steels under complex strain-path changes 

      Qin, Jisheng; Holmedal, Bjørn; Hopperstad, Odd Sture (Journal article; Peer reviewed, 2018)
      In this work, a new model is proposed for predicting stress transients caused by strain path changes. The model is formulated in stress space, where a second order tensor, i.e., the microstructure stress deviator, is used ...
    • A comparative study of beam element formulations for nonlinear analysis: corotatinal vs. geometrically exact formulations 

      Mathisen, Kjell Magne; Bazilevs, Yuri; Haugen, Bjørn; Helgedagsrud, Tore Andreas; Kvamsdal, Trond; Okstad, Knut Morten; Raknes, Siv Bente (Chapter, 2017)
      In this work the geometrically exact three-dimensional beam theory has been used as basis for development of a family of isoparametric higher order large deformation curved beam elements. Geometrically exact three-dimensional ...
    • A density-dependent failure criterion for concrete 

      Øverli, Jan Arve (Journal article, 2016)
      This work focuses on the large effect of small secondary stresses on the compressive strength of concrete. The strength and especially the ductility of structural concrete members depend on local triaxial stress conditions ...
    • Adsorption Isotherms for Lignosulfonate in Cement with Fly Ash and Blast Furnace Slag 

      Aasheim, Marius Ekanger (Master thesis, 2016)
      Plasticizers are used to increase the workability of cement in its fresh state. When adding plasticizers to a paste, the molecules chemically adsorb on the surface of cement particles. This interaction between the plasticizer ...
    • A dynamic analysis of Skuteviksboder in Bergen and alternative load-bearingsystems 

      Fossdal, Fredrik Myking; Alvær, Ragnhild Marie (Master thesis, 2010)
      A seismic analysis of Skuteviksboder is carried out by a simplified hand calculation in addition to a computation by the analytical program FEM-design. Alternative load-bearingsystems are discussed as well. The theory that ...
    • Aerodynamic Response of Slender Suspension Bridges 

      Gudmundsson, Birgir Fannar (Master thesis, 2016)
      The design and construction of the new coastal highway E39 along the west coast of Norway involves great challenges due to the large width and depth of the fjords along the coast. The new bridges involved in this project ...
    • Aerodynamic Response of Slender Suspension Bridges 

      Aaland, Jens Einar (Master thesis, 2014)
      During the planning of long, slender suspension bridges a lot of aerodynamics has to be taken into account. This thesis focus on one phenomenon; vortex induced vibrations. The purpose of the work has been to learn theory ...
    • Aerodynamic Stability of Long-span Suspension Bridges 

      Dalen, Magnus Aa (Master thesis, 2016)
