Mojtaba Rahimi, Dave Chan, Alireza Nouri
This paper presents a critical state constitutive model for cemented sand. The model uses a single capped yield surface as a function of the void ratio, confining pressure, preconsolidation pressure, and stress ratio at the peak of the undrained effective stress path. To model the cemented...

Abstract: In very loose sand, the ratio M-p of shear stress to mean normal stress at the peak point of the undrained effective stress path (UESP) is very close to the stress ratio M at the peak point of the capped yield surface. Stress ratios M-p can therefore be used in constructing yield...

Chan, D. H., Morgenstern, N. R., Robertson, P. K., Imam, S. M. R.
Abstract: The relationship between the shapes of the yield surface and the undrained effective stress path (UESP) of loose sand is investigated for triaxial loading conditions. It is shown that the UESP can be used in the construction of capped yield surfaces for sands. The stress ratio M-p...
