“…c 0 = 0.001, is the state parameter, and both and k m are model parameters. With sufficiently small value of c 0 , Equation (12) behaves similar to Equation (15) in Liu et al [25] when the shear stress ratio is non-trivial. The dilatancy approaches a very large value with very small , reproducing the interface behavior under pure compression.…”

“…For dense interfaces, there exists a phase transformation stress ratio M d smaller than the critical state stress ratio M c , at which the dilatancy is zero, which is similar to the property of sand. Although the stress-dilatancy relationship used in Liu et al [25] can describe such behavior, the plastic-flow direction when the shear stress is zero could still induce shear plastic strain using that stress-dilatancy relationship [39]. Observing that, the dilatancy of the interface is reformulated as…”

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.

This volume gives an overview on the main modeling methods developed in geotechnical engineering in order to describe the SSI in various situations:Copyright Iste 2022 / File for personal use of Robert Charlier onlyx Deterministic Numerical Modeling of Soil-Structure Interaction -The classical and well-known finite element method (FEM) using interface or contact elements available for coupled hydro-mechanical problems and in which the local plastic energy dissipation contributes to the classical global damping.-The distinct element method (DEM) in which the contact zones between soil and structure are described by local adapted interaction laws.-The finite difference method (FDM) using explicit algorithm in which interface or contact elements are available and straightforward for coupled hydro-mechanical, highly nonlinear with high deformation and dynamic problems.-The more recent approaches based on the macro-element concept and generalized variables in an incremental form available in static and dynamic situations, where a large volume of soil underlying and surrounding the-structure is represented by a small number of degrees of freedom. This method could be considered as an improved extension of the stiffness coefficient methods known for the piles as the t-z and p-y curves.-The seismology approach with inertia and viscous equivalent damping forces, in which the SSI is developed between several structures (like buildings in a town) using the notion of meta-materials. This point of view is especially useful when analyzing the movement of the buildings induced by a seismic event at the scale of a town.
