    • Anisotropic sand model and fabric evolution until the critical state 

      Papadimitriou, A. G.; Dafalias, Y. F.; Li, X. S. (2014)
      This paper presents a simple anisotropic sand model within a recently proposed anisotropic critical state theory (ACST). The model adopts the SANISAND constitutive model platform and uses a fundamental ingredient of ACST, ...

    • Effect of soil characteristics on shear strength of sands 

      Tyri D., Kallioglou P., Koulaouzidou K., Apostolaki S. (2018)
      The paper presents the results of a laboratory investigation into the influence of (a) mineral composition and angularity of sand grains and (b) fines type and content on the strength parameters of sandy soils tested at ...

    • Effect of yield surface shape on the simulated elasto-plastic response of cohesive soils 

      Papadimitriou, A. G.; Vranna, A. D.; Dafalias, Y. F.; Manzari, M. T. (2010)
      This paper presents a discussion on the effect of the selected yield surface shape on the simulated drained and undrained response of cohesive soils. The discussion is made possible by sequentially implementing two different ...

    • Sand model within anisotropic critical state theory with evolving fabric 

      Papadimitriou, A. G.; Dafalias, Y. F.; Li, X. S. (2015)
      This paper presents a simple anisotropic sand model within a recently proposed Anisotropic Critical State Theory (ACST), which was motivated by grain level kinematics studied by means of DEM. The model adopts the SANISAND ...

    • SANICLAY: A new simple anisotropic clay plasticity model 

      Papadimitriou, A. G.; Dafalias, Y. F.; Manzari, M. T. (2007)
      SANICLAY is a new simple anisotropic clay plasticity model that builds on a modification of an earlier model with an associated flow rule, in order to include simulations of softening response under undrained compression ...
