Particle breakage and constitutive modeling of granular soil-structure interfaces. Saberi, M., Annan, C., & Konrad, J. In volume 2, pages 741 - 748, Vancouver, BC, Canada, 2017. Constitutive formulation;Critical interfaces;Different soils;Mechanical behavior;Model prediction;Particle breakage;Plasticity model;Volumetric behavior;abstract bibtex Particle breakage occurs in granular soil-structure interface zones in different soil-structure interaction (SSI) systems under cyclic loading, and it largely affects the performance of these structures. The effect of particle breakage on mechanical behavior of granular soil-structure interfaces should be taken into account in an interface constitutive model for accurate simulating the SSI problems with critical interfaces. In this study, the effect of particle breakage on the mechanics of granular soil-structure interface is presented. An approach is then proposed to improve an elasto-plastic interface constitutive models to be capable of simulating particle breakage under shear loads. The effectiveness of the approach is evaluated using an interface constitutive model to predict the volumetric behavior of a granular soil-structure interface under different stress path. The model predictions are then compared with experimental observations. It is illustrated that the particle breakage has significant effect on the compressibility behavior of the granular soil-structure interface, and it can be well addressed within the constitutive formulations of an interface plasticity model.
