Numerical implementation of advanced soil constitutive models: finite element method and applications [PDF]

Numerical analysis of various problems involving the hydro-mechanical or thermo-mechanical coupling of soils remains a challenge in the geotechnical engineering. An important element in a coupled analysis is the constitutive model adopted for the soil. A

A COUPLED HYDRAULIC-MECHANICAL ELASTOPLASTIC CONSTITUTIVE MODEL FOR UNSATURATED SANDS AND SILTS [PDF]

, 2009
Unsaturated soils are three-phase porous media consisting of a solid skeleton, pore water, and pore air. It is well known that the behavior of unsaturated soils is influenced heavily by the matric suction (pore air pressure minus pore water pressure ...

Return Mapping Technique for the Extended Subloading Surface Model with Tangential Plasticity

Return Mapping Technique for the Extended Subloading Surface Model with Tangential Plasticity
Most of the phenomenological elastoplastic models adopting a plastic flow rule with a single yield surface tend to predict an unrealistic material response especially when they are subjected to the non-proportional loading condition with a sudden change of the loading path.

EXTENDED TANGENTIAL-SUBLOADING SURFACE MODEL FOR GENERAL LOADING BEHAVIOR OF SOILS : APPLICATION TO NONPROPORTIONAL LOADINGS

EXTENDED TANGENTIAL-SUBLOADING SURFACE MODEL FOR GENERAL LOADING BEHAVIOR OF SOILS : APPLICATION TO NONPROPORTIONAL LOADINGS
The conventional elastoplastic model premising that the interior of yield surface is a purely elastic domain is incapable of describing the plastic deformation by the rate of stress inside the yield surface. Thus, it is inapplicable to the description of cyclic loading behavior.
