DEM investigation on the effect of sample preparation on the shear behavior of granular soil

- Effect of initial fabric anisotropy on the shear behavior of granular soil was investigated.
- The stress-dilatancy relationship was less affected by the initial fabric anisotropy.
- Various anisotropy indices tended to reach a common steady state at large shear strains.
- Fabric and force anisotropy accounted for the main contribution to the mobilized friction angle.
- A unique critical state line could be identified in both e-log p′ and q-p′ plots.
