    • Creep of geomaterials – some finding from the EU project CREEP 

      Grimstad, Gustav; Karstunen, Minna; Jostad, Hans Petter; Sivasithamparam, Nallathamby; Mehli, Magne; Zwanenburg, Cor; Evert, den Haan; Ghoreishian Amiri, Seyed Ali; Boumezerane, Djamalddine; Kadivar, Mehdi; Haji Ashrafi, Mohammad Ali; Rønningen, Jon A. (Peer reviewed; Journal article, 2017)

    • Modelling creep behaviour of anisotropic soft soils 

      Sivasithamparam, Nallathamby; Karstunen, Minna; Bonnier, Paul (Journal article, 2015)
      This paper presents a three dimensional constitutive model that describes the creep behaviour of natural clays with anisotropic stress–strain response, focussing on robust model implementation. Creep is formulated using ...

    • Permissible range of model parameters for natural fine-grained materials 

      Gras, Jean-Philippe; Sivasithamparam, Nallathamby; Karstunen, Minna; Dijkstra, Jelke (Peer reviewed; Journal article, 2017)
      This paper presents a three-dimensional constitutive model for natural clay that includes creep, anisotropy and structure, as well as a theoretical means to estimate the range for anisotropy- and structure-related parameters, ...

    • Stone column settlement performance in structured anisotropic clays: the influence of creep 

      Sexton, Brian; Mc Cabe, Bryan A.; Karstunen, Minna; Sivasithamparam, Nallathamby (Journal article, 2016)
      The recently developed elasto-viscoplastic Creep-SCLAY1S model has been used in conjunction with PLAXIS 2D to investigate the effectiveness of vibro-replacement in a creep-prone clay. The Creep-SCLAY1S model accounts for ...
