The mechanical behavior of dry and saturated sands not only depend on the current void ratio and effective stress but also on their deposition method. This latter can be reproduced in the laboratory by considering samples with different preparation methods. In this work, an extension to an existing constitutive model for sands is presented to account the inherent fabric effects. The reference constitutive model corresponds to the ISA (Intergranular Strain Anistropy) model, which has been recently proposed to simulate sandy materials under static and dynamic analysis. The formulation of the inherent fabric assumes an initial isotropic structure typical of sands with predominant round shaped particles. Some simulations with the Karlsruhe fine sand are at the end analyzed considering two different preparation methods.
