Abstract

Abstract

A mixed strain hardening constitutive model,which can describe the induced anisotropy of soils,is proposed combining the rotational hardening mechanism with the unified hardening model.The drained stress path for clay and the undrained stress path for sand are predicted using the proposed model.It is indicated that the proposed model can describe both the stress-strain relationship of clay and the stress-strain relationship of the saturated sand under various cyclic loading conditions well.
- unified hardening model,
- over-consolidated clay,
- rotational hardening
