The effect of initial fabric anisotropy produced by sample preparation on the shear behavior
of granular soil is investigated by performing discrete element method (DEM) simulations of
fourteen biaxial tests in drained conditions. Numerical test specimens are prepared by three
means: gravitational deposition, multi-layer compression, and isotropic compression, such
that different initial inherent soil fabrics are created. The DEM simulation results show that
initial fabric anisotropy exerts a considerable effect on the shear behavior of granular soil …
