Shear band formation in granular media as a variational problem.
Strain in sheared dense granular material is often localized in a narrow region called the shear band. Recent experiments in a modified Couette cell provided localized shear flow in the bulk away from the confining walls. The nontrivial shape of the shear band was measured as the function of the cell geometry. First, we present a geometric argument for narrow shear bands that connects the funct...
متن کاملProbing the shear-band formation in granular media with sound waves.
We investigate the mechanical responses of dense granular materials, using a direct shear box combined with simultaneous acoustic measurements. Measured shear wave speeds evidence the structural change of the material under shear, from the jammed state to the flowing state. There is a clear acoustic signature when the shear band is formed. Subjected to cyclic shear, both shear stress and wave s...
متن کاملInfluence of particle shape on shear band formation of quasistatic granular media
We study the influence of particle shape on the shear band formation in quasistatic granular media in biaxial compression test using two-dimensional Distinct Element Method (DEM). Elliptical-shaped particles are used to study the influence of particle shape. We also report an experimental verification to check the ability of DEM to model elliptical particles created by the clustering technique....
متن کاملDrop formation in shear-thickening granular suspensions.
We study droplet formation in granular suspensions by systematically varying the volume fractions (φ) and particle diameters (d). For suspensions with water as the suspending liquid, we find three different regimes. For dilute suspensions (φ≤45%), drop formation follows the predictions for inertial breakup and exhibits identical dynamics to that of pure water. The breakup is strongly asymmetric...
متن کاملShear Band Formation in Bulk Metallic Glasses
In recent times, there has been a growing interest in the machining of amorphous metallic alloys, which are also called bulk metallic glasses (BMGs). These materials differ from common polycrystalline metallic alloys, because their atoms do not assemble on a crystalline lattice, and as a result, they have unique physical, mechanical, and chemical properties. A number of BMGs have been found to ...
