ABSTRACT
SANICLAY is a simple anisotropic plasticity model proposed by Dafalias et al (2006) that provides relatively satisfactory simulation of the rate-independent behavior of both normally consolidated and overconsolidated sensitive clays which do not exhibit destructuration during loading. An extension to include destructuration was recently published by Taiebat et al. (2009). SANICLAY builds on a modification of the associative flow rule isotropic Modified Cam Clay (MCC) model (Burland 1965), at the expense of merely three extra constants. In fact, its reference model (Dafalias 1986) constitutes the simplest possible energetic extension of the MCC model from isotropic to anisotropic response.
