“…Numerous authors have proposed constitutive models to tackle the behaviour of soil specimens subjected to grain crushing and large shear displacements, namely at the interface level (Desai & Ma, 1992;Gennaro & Frank, 2002;Mortara, Boulon, & Ghionna, 2002), in order to simulate geotechnical structures. A brief summary of some of the models is presented henceforth.…”

Soil is subjected to shear stress and/or displacements in numerous geotechnical applications. This leads to a large number of numerical models being developed to represent its behaviour under various stress paths. This paper aims to present a sound mechanical formulation for finite strains and to introduce a rational constitutive model to match realistically the behaviour of soil where, for a high range of deformations, strains localise and the phenomenon of grain breakage is usually observed in granular soil. The reference model is the ECP's constitutive model (also known as "Hujeux's model"), which is an elastoplastic multimechanism model. An overview is made of laboratory results and constitutive relations that consider finite deformation, and the grain breakage phenomenon that is usually associated with it in granular materials. The performance of the proposed constitutive model is demonstrated simulating constant volume ring shear tests carried out on Ottawa (OT) and Illinois River (IR) sands up to very high shear strains and comparison of the obtained results with laboratory testing data.

SUMMARYThe cyclic behavior of soil-structure interface can be very important in dynamic problems. The cyclic behavior of soil-structure interface may be nonlinear, which includes hysteresis, hardening, degradation, and particle breakage. The breakage of granular soil particles during shearing of granular soil-structure interface is associated with cyclic degradation and can be critical to the dynamic behavior of soilstructure system. The critical state soil mechanics concept formerly used to simulate the nonlinear monotonic behavior of granular soil-structure interface was modified and extended to describe the cyclic behavior, especially soil-particle breakage and degradation during cyclic shearing. Soil-particle breakage was assumed to relate to the energy consumption during cyclic shearing and the critical state line of the soil-structure interface was assumed to translate with the consumption of shearing energy during cyclic shearing as the threshold value is attained. The model was formulated in the framework of generalized plasticity and is capable of describing the salient features of granular soil-structure interface under cyclic loading. Most of the model parameters have straightforward physical meanings and are calibrated using monotonic or cyclic interface test results. The proposed model was calibrated and validated against published test results. The dependency of interface behavior on stress path and cyclic degradation can be successfully described by the proposed model.
