Abstract

The macroscopic behavior of sands is closely related with its microstructure. Starting from the microstructure of sands, using micromechanics and integrated with statistically homogenization, considering intergranular contact force and branch vector, the paper focuses on the expressions for macroscopic stress; Integrated with the fabric characteristics of granular material, the second-order fabric tensor F is derived, and the relationship between stress-force-fabric is established. It shows that the macroscopic stress of sands is closely directed with inherent and stress-induced anisotropy, and the tendency between shear strength and fabric is same which lay the foundation for the following constitutive relationship for sands.
