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, ...

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 ...
