“…Some researchers considered 13 planes in different directions of a sphere with a radius of one; they modelled effects of anisotropy for different models (Sadrnejad, 2009;Sadrnejad and Karimpour, 2011;Sadrnejad and Labibzadeh, 2006). The recent model has been problematic due to the number of planes, preparation of simultaneous conditions, strain consistency, and equilibrium (Ghadrdan and Sadrnejad, 2015;Sadrnejad and Labibzadeh, 2006).…”

“…Therefore, the multilaminate constitutive modelalso known as micro-plane in some sources (Bazant et al, 1996;Caner and Bazant, 2000)-is a suitable mechanism for the simultaneous prediction of complete anisotropy in sandy soil in terms of material behaviour in different planes. This model has been evaluated for different materials, such as soil Sadrnejad, 2009;Sadrnejad and Karimpour, 2011), and for the estimation of damage models in concrete (Ghadrdan and Sadrnejad, 2015;Sadrnejad and Labibzadeh, 2006).

The estimation of the value and direction of post-liquefaction deformations is one of the most challenging issues in the modelling of liquefaction soil, due to the inherent and induced anisotropy. It is very important in the science of soil-constitutive models to present a simple and comprehensive model for the prediction of fabric anisotropy effects in pre-and post-liquefaction behaviour in granular soil. In the framework of the multilaminate method, 17 planes with predetermined directions are defined, instead of defining all occurrences depending on the direction in three planes perpendicular to each other in a Cartesian coordinate system. As a result, calculation accuracy is increased in the point due to the effectiveness of the behaviours in different directions. In the present study, after modifying an advanced model by removing constants related to the fabric effect and using lower constants, the precision of model performance after the removal of constants was studied and compared with experimental results in different monotonic, cyclic, drained, and undrained loading conditions. After this, the formation of stress and strain in 17 planes was evaluated in terms of pre-and post-liquefaction, with monotonic and cyclic loadings. The study of the curves shows induced anisotropy in different directions of sandy soil and thus proves the capability of the model in this regard.
