Dilatancy-induced surface deformation in dense cohesive granular media
Huzaif Rahim, Thorsten Poeschel, Sudeshna Roy
When granular materials with interstitial liquid bridges are sheared in a split-bottom cell, a localized shear band develops, accompanied by a surface elevation. Cohesion, governed…
Shear-induced pressure anisotropy in granular materials of nonspherical particles
Huzaif Rahim, Sudeshna Roy, Thorsten Pöschel
When a granular material composed of elongated grains is sheared in a split-bottom shear cell, a pressure difference develops within the material. This pressure difference depends…
Impact of friction and grain shape on the morphology of sheared granular media
Huzaif Rahim, Sudeshna Roy, Thorsten Pöschel
The interplay between dilatancy and particle alignment in sheared granular materials composed of non-spherical particles leads to morphological inhomogeneity. Dilatancy, driven by…
Alignment-induced depression and shear thinning of anisotropic granular media
Huzaif Rahim, Vasileios Angelidakis, Thorsten Pöschel +1
When granular materials of shape-anisotropic grains are sheared in a split-bottom shear cell, a localized shear band is formed with a depression at its center. This effect is close…
