Abstract
Soft clays are normally consolidated or lightly overconsolidated soils where even small increases of stresses are likely to cause non-linearity and plasticity in their response. In addition, soft clays have a significant degree of anisotropy in their natural state that adds to the complexity of their behaviour. In this paper a new model is
proposed by extending the anisotropic critical state-based model S-CLAY1 with a bounding surface formulation. Both isotropic and rotational hardening rules are incorporated into the bounding surface
formulation with an associated flow rule. The new model is shown to capture well the important aspects of observed response during cyclic loading of natural clays such as anisotropy, hysteresis, accumulation of permanent strains and loading-unloading cycles
