• Ductile-Brittle Transition in Offshore Steel 

      Hellum, Gry Myrmo (Master thesis, 2017)
      The main objective of this thesis was to investigate experimentally and numerically the main effects and interaction effects of temperature, strain rate and stress triaxiality on an offshore X65 steel. During preliminary ...
    • Micromechanical Modelling and Simulation of Ductile Fracture in Metallic Materials 

      Bergo, Sondre (Master thesis, 2016)
      This thesis is concerned with the modeling of a cellular automaton model of ductile fracture in metals involving significant micro-structure heterogeneities, based on the growth equations of Rice\&Tracey for the microvoids ...
    • Simulation of Ductile Crack Propagation in Steel Pipes 

      Sterner, Elise; Skarstein, Mari (Master thesis, 2018)
      For the transport of gases and liquids, such as CO2, in steel pipelines to be safe, rupture in the pipe should be avoided. A crack in a pressurized pipe may start to propagate rapidly along the pipeline and run for ...
