Finite element modelling of soft sensitive clays: Regularisation by the non-local strain method or rate dependency and pore water flow
Rødvand, Laura Anne (Doctoral theses at NTNU;2023:55, Doctoral thesis, 2023) -
Modelling mesh independent failure loads of a soft strain-softening clay using a rate dependent model
Rødvand, Laura Anne; Jostad, Hans Petter; Grimstad, Gustav; Andresen, Lars (Peer reviewed; Journal article, 2023)If no regularisation method is used during finite element modelling of strain-softening (brittle) materials, results become mesh dependent: manifesting as very thin shear bands whose thickness and orientation depends on ... -
Strain localisation in sensitive clays: can rate dependency provide mesh independent results?
Rødvand, Laura Anne; Jostad, Hans Petter; Grimstad, Gustav; Andresen, Lars (Peer reviewed; Journal article, 2022)Finite element modelling involving strain-softening materials becomes mesh dependent if not regularised by a mesh independent length scale. The objective of this paper is to investigate whether the inherent strain rate ...
