Hence, a revised analytical formulation is proposed, which takes into account both above effects of sand fabric evolution.
In all cases, significantly larger dilation and fabric evolution are observed inside the shear band than outside.
In the case of smooth boundary condition, structural constraint dominates over the fabric evolution and leads to the formation of a single shear band.
When the boundary condition is rough, the structural constraint may play a comparable role with fabric evolution, which leads to symmetric cross-shape shear bands.
It is shown that their basic mathematical assumption for the rate of earthquake-induced excess pore pressure generation overlooks sand fabric evolution effects during cyclic loading and eventually leads to underestimation of the drain effectiveness.
This relation was considered unique in the original work, for reasons of simplicity, thus neglecting sand fabric evolution effects that may differentiate it for various sands, densities and loading conditions.

The inherent fabric evolutions based on contact normal and particle orientation were explored.
This hidden genetic diversity is the very fabric of evolution —the key to future adaptation and the flexibility of life.
This paper presents a numerical study on strain localization in sand, with a special emphasis on the influence of soil fabric and its evolution on the initiation and development of shear band.
This paper presents a bounding surface plasticity model for sand that considers fabric and its evolution during monotonic shearing.
In particular, a critical state sand plasticity model accounting for the effect of fabric and its evolution is used in the finite element analysis of plane strain compression tests.
