Evolution of Fabric in the Shearing Process Based on Micromechanics
In this paper a new formulation is presented to encompass the induced anisotropy during shear deformation in granular mass.The fabric anisotropy is affected by a number of parameters such as the mobilized stress ratio,internal friction angle,and the state of fabric.Non-coaxiality between stress and fabric tensor is included in this equation.This proposed formulation is derived by considering the interaction of particles across a potential sliding plane at microlevel.It is further developed to incorporate the initial fabric anisotropy.The changes of fabric in the presence of inherent anisotropy will be predicted by these equations.Verifying of the formulation is presented with numerical simulations and experimental tests.
