... shearing histories, combined with advanced image analysis to track microstructural evolution directly. A counterintuitive response was observed: the apparently densest specimen exhibited the lowest initial stiffness and dilatancy, attributed to preshearing-induced fabric anisotropy. Particle rotations were...

...Xiaoqiang Gu; Xiaomin Liang; Jing Hu Fabric anisotropy is a sought-after micro index to correlate macro mechanical responses of granular materials. In this work, the discrete-element method is utilised to simulate multi-directional bender element tests in granular soils to obtain the evolution...

... and G_0(ij) more anisotropic. The proposed model can effectively predict the observed anisotropy of G_0(ij) under isotropic and anisotropic loading conditions. The new model also offers a new method for determining the fabric anisotropy of sand based...
