THE APPLICATION OF AN ANISOTROPIC HARDENING MODEL IN THE ANALYSIS OF ELASTO-PLASTIC DEFORMATION OF SOILS

This paper extends the previous work by the authors where an anisotropic hardening model for soils was proposed, taking into account both isotropic hardening due to porosity changes and anisotropy effects induced by the initial consolidation process. The analysis is restricted to the case of triaxial state for which two principal stresses are equal. The incremental relations are derived and applied to study the drained and undrained material behaviour after isotropic and anisotropic ko consolidation of clays. The material response under cyclic loading is also discussed. The predicted inelastic behaviour is compared with available experimental results for kaolin and weald clays for which the material parameters are also identified. Further improvements of the model are indicated. /Author/TRRL/
