A state-dependent hyperelastic-plastic constitutive model considering shear-induced particle breakage in granular soils

Abstract An elastic–plastic constitutive model considering particle breakage for simulation of crushable granular soils behavior is proposed. In the model, elastic strain rates are derived from a modified Helmholtz free energy function, and influence plastic shear work-induced on properties sand taken into account as an coupling mechanism. A stress ratio-driven mechanism employed calculation rates. The proposed capable tracking evolution grain size distribution (GSD) due to shear-induced breakage. evolving index Einav (2007) (J Mech Phys Solids 55(6):1274–1297, 2007) interrelated work avoid overestimation in loose sands. direct comparison between simulations laboratory data has been carried out five series drained/undrained monotonic cyclic triaxial tests covering wide range initial states. For sake comparison, predicted behaviors hypoplastic specially developed also included. It shown that can provide reasonable predictions using single set parameters each data.
