    • Stability analyses of quick clay using FEM and an anisotropic strain softening model with internal length scale 

      Grimstad, Gustav; Jostad, Hans Petter (Chapter, 2012)
      Sensitive soft clays generally display a significant post peak strain softening response under undrained deformation. A consequence of this behavior is that the safety factor during undrained stress changes cannot be ...

      Aas, Gunnar; Lacasse, Suzanne (NGI Publication;209, Chapter, 2022)
      Norway and Sweden have been subjected to landslides for several centuries, with some of the largest landslides involving a large block sliding out as a continuous flake on a deposit of soft quick clay. Attempts to calculate ...
