A previously introduced two phase model was used to assess its capability in predicting the behavior of reinforced soil walls under working stress conditions. The two phase model is a homogenization method based on the virtual work theorem. The reinforced soil medium is considered as the superposition of two continuous phases, the reinforcement and matrix phases that interact within the medium....

In this paper, pile behavior embedded in layered soil deposits subjected to seismic loadings is analyzed using a nonlinear fiber element for simulation of soil – pile interactions. In the created model, both pile and surrounding soil are modeled using fiber elements in a practical Beam on Nonlinear Winkler Foundation (BNWF) concept. Herein, the features of DRAIN–3DX finite element software are ...

The creep problems are often involved in soil under cyclic loading, and its behaviors of loading sparks many arguments current research field. To propose one new model to demonstrate these the was simplified equivalently, elastic-viscoplastic (EVPM) for established based on Bingham model. yield criterion with constant amplitude proposed following load. A constitutive equation EVPM constructed b...

Deformation of quay walls is one of the main sources of damage to port facility while liquefaction of backfill and base soil of the wall are the main reasons for failures of quay walls. During earthquakes, the most susceptible materials for liquefaction in seashore regions are loose saturated sand. In this study, effects of enhancing the wall width and the soil improvement on the behavior of gr...

In this paper, an efficient two-dimensional finite element model for a mooring cable and seabed interaction is built while geometric shape and tensions of the cable are computed in time domain. In the model, a hybrid beam element is employed to simulate the mooring cable with the seabed simulated by different soil constitutive models. When the elastic and elastic-plastic soil constitutive model...

M. Maleki,

In this paper, an elastoplastic constitutive model is presented for predicting sandy soil behavior under monotonic and cyclic loadings. The model is based on the CJS3 model that takes into account deviatoric and isotropic mechanisms of plasticity. The flow rule in deviatoric mechanism is non-associated and a kinematic hardening law controls the evolution of the &#10yield surface. In the present...
