In this paper the application of the mesh-free method (MFM) for the elasto-plastic analysis of reinforced soils is studied for the first time. The applied mesh-free method is called the radial point interpolation method (RPIM). In MFM, unlike the finite element method (FEM), there is no need of mesh in the traditional sense, and the shape functions are based on nodes. In the present study the r...

This paper presents a unified approach to model the influence of fabric anisotropy 6 and its evolution on both the elastic and plastic responses of sand. A physically based fabric 7 tensor is employed to characterize the anisotropic internal structure of sand. It is incorporated 8 into the nonlinear elastic stiffness tensor to describe anisotropic elasticity, and is further 9 included explicitl...
