Elasto-Plastic Constitutive Model for Bonded Sand over a Wide Stress Region
A constitutive equation of sand in which the particles are weakly bonded at contact was proposed. The proposed equation was developed on the basis of critical state and subloading surface concepts. The effect of bonding on the mechanical behavior of sand was quantified as an internal stress component. The degradation of bonding caused by loading was modeled as an evolution law of the internal stress. Analysis of the specifics of internal stress degradation played an indispensable role in developing a valid model of bonded sand.
