摘要: In this paper the mobilized stress ratio is investigated by using static equilibrium at micro scale level analysis. The obtained in distribution of contact normal, E (β ), and inter-particle friction angle, ϕμ . second invariant fabric tensor, α used to account for its evolution. There a difference between theoretical rotation principal axes that classical equations mechanics materials experimental axes. related anisotropic parameter, noncoincidence relative direction plane bedding plane. A comparison with tests demonstrates validity formulation.
