A Double-Yield-Surface Elastoplastic Constitutive Model for Cemented Sand and Gravel Dam Materials
Cemented sand and gravel (CSG) exhibits distinct shear and volumetric deformation responses. This study assesses a double-yield-surface incremental formulation and recalibrates its axial and volumetric response relations using coordinates digitized from the available triaxial plots. Three binder contents, 20, 60, and 1...
