    • A procedure for the assessment of the undrained shear strength profile of soft clays 

      Thakur, Vikas Kumar Singh; Fauskerud, Odd Arne; Gjelsvik, Vidar; Christensen, Stein Olav; Oset, Frode; Nordal, Steinar; Viklund, Margareta; Strand, Stein-Are (Chapter, 2016)
      In the geotechnical research community, there is widespread agreement that the choice of the characteristic undrained shear strength (cuA) is very important and plays an essential role in the design and stability analysis ...

    • Adaptive isogeometric finite element analysis of steady-state groundwater flow 

      Bekele, Yared Worku; Kvamsdal, Trond; Kvarving, Arne Morten; Nordal, Steinar (Journal article; Peer reviewed, 2015)
      Numerical challenges occur in the simulation of groundwater flow problems because of complex boundary conditions, varying material properties, presence of sources or sinks in the flow domain, or a combination of these. In ...

    • Isogeometric analysis of THM coupled processes in ground freezing 

      Bekele, Yared Worku; Kyokawa, Hiroyuki; Kvarving, Arne Morten; Kvamsdal, Trond; Nordal, Steinar (Journal article; Peer reviewed, 2017)
      An isogeometric analysis (IGA) based numerical model is presented for simulation of thermo-hydro-mechanically (THM) coupled processes in ground freezing. The momentum, mass and energy conservation equations are derived ...

    • Mixed Method for Isogeometric Analysis of Coupled Flow and Deformation in Poroelastic Media 

      Bekele, Yared Worku; Fonn, Eivind; Kvamsdal, Trond; Kvarving, Arne Morten; Nordal, Steinar (Peer reviewed; Journal article, 2022)
      Pressure oscillations at small time steps have been known to be an issue in poroelasticity simulations. A review of proposed approaches to overcome this problem is presented. Critical time steps are specified to alleviate ...
