Models

S-CLAY1S is an elasto-plastic model that account for initial and plastic strain induced anisotropy via a rotational hardening law. In addition, the model accounts for bonding and destructuration by using the concept of an intrinsic yield surface. By setting the model parameter controlling bonding to zero, S-CLAY1S reduces to S-CLAY1 model that accounts for anisotropy only, and furthermore, by setting the parameters related to anisotropy to zero, S-CLAY1S reduces to the isotropic Modified Cam Clay model. The values for the model parameters for S-CLAY1 and MCC models can be derived from conventional oedometer and triaxial shear tests (CU or D). In order to model bonding and destructuration with the S-CLAY1S model, an oedometer test on reconstituted sample is required together with a measure of the sensitivity.
