Xiong Zhang, Auteur ; Juanyu Liu, Auteur ; Li Peng, Auteur |Attention is increasingly paid to the elastoplastic behavior of unsaturated soils. In the development of an elastoplastic framework for unsaturated soils, it is necessary to determine the initial shape of the yield curve and its evolution with y[...]

Xiong Zhang, Auteur ; Jean-Louis Briaud, Auteur |Constitutive surfaces are indispensable for investigation of the behavior of soils. Saturated and unsaturated soils coexist in most engineering problems and it is meaningful to develop constitutive surfaces covering both saturated and unsaturate[...]

Xiong Zhang, Auteur ; Robert L. Lytton, Auteur |The traditional state-surface approach to the study of unsaturated soil behavior is becoming much less popular these days, as it uses unique constitutive surfaces to represent unsaturated soil behavior. This approach is essentially a nonlinear e[...]

Xiong Zhang, Auteur ; Robert L. Lytton, Auteur |In the previous companion paper, a modified state-surface approach was proposed to algebraically represent unsaturated soil behavior under isotropic stress conditions. The present paper proposes a general theoretic formulation for the modified s[...]
