.... The effects of the overconsolidation ratio and initial state parameter are extensively investigated for various clay types. Both theoretical and empirical correlations are then proposed for back-calculations of cone factor, undrained shear strength, overconsolidation ratio and initial state parameter of clays...

... significantly on the state parameter (ψ), but it was significantly affected by the stress path followed during consolidation and subsequent shear, for example, by the pre-shearing stress ratio, stress-reversal loading, θ and α. The results demonstrate the contribution of the initial...

...M. T. Manzari; Y. F. Dafalias Within the critical state soil mechanics framework, the two-surface formulation of plasticity is coupled with the state parameter to construct a constitutive model for sands in a general stress space. The operation of the two-surface model takes place in the deviatoric...
