Practical nonlinear constitutive model for rockfill materials with application to rockfill dam
Computers and Geotechnics, 2020Abstract In this paper, a nonlinear constitutive model for rockfill materials is proposed to account for the coupling influence of the mean effective stress p and the deviatoric stress q on the deformation of rockfill materials. In the model, the stress-dilatancy relationship derived from the microstructural changes of granular materials is adopted ...

Evaluation of Properties of Rockfill Materials
Journal of the Soil Mechanics and Foundations Division, 1972A modeling technique has been used to determine the properties of rockfill materials. The results indicate that the mechanical properties of the field rockfill materials can be predicted with a high degree of accuracy by a series of tests with modeled rockfill materials in the laboratory. Modeling of the rockfill materials did not materially affect the
