Abstract: By representing the assembly by a simplified column model, a constitutive theory was recently developed for a two-dimensional assembly of rods. This theory, referred to as the sliding-rolling theory, is extended in this ...

Abstract: An anisotropic constitutive model was recently presented for describing the stress–strain behavior of granular materials with considerations for the initial and induced anisotropy. The model was developed within the framework ...

Abstract: When a water-saturated clayey soil is leached with an organic fluid such as heptane, it has been found that under some conditions the hydraulic conductivity (or the permeability) increases manyfold. While it is generally ...

Abstract: By analyzing a microelement based on four spheres, equations governing the equilibrium of the microelement are developed. By examining these equations more closely, two primary mechanisms of failure of the microelements, ...

Abstract: The effect of using an isotropic soil plasticity model to analyze the behavior of a sheet-pile wall supporting an anisotropic cohesive soil is investigated numerically using the finite element method. The stress-strain ...

Abstract: When subjected to undrained cyclic loading, cohesionless soils are known to build up pore‐water pressure to the extent that the soil loses the effective confining pressure completely, leading to what is known as liquefaction. ...

Abstract: The discrete‐element method has successfully been applied in the past to study constitutive behavior of granular materials. The method is applied in this paper to cohesive soils, where in addition to mechanical forces, ...

Abstract: Due to the existence of physicochemical effects, the pore fluid type generally has a significant influence on the geotechnical behavior of clays. The present paper focuses on the stress-strain and shear-strength behavior ...

Abstract: In a clay-water-electrolyte system, there exists a double-layer repulsive force between the clay particles. In a recent study, the influence of the nonparallel orientation and the finite size of the clay particles are ...
