Critical packing in granular shear bands [PDF]
Physical Review E, 2007 In a realistic three-dimensional setup, we simulate the slow deformation of idealized granular media composed of spheres undergoing an axisymmetric triaxial shear test.

Fluid Depletion in Shear Bands [PDF]
Physical Review Letters, 2012 How does pore liquid reconfigure within shear bands in wet granular media? Conventional wisdom predicts that liquid is drawn into dilating granular media. We, however, find a depletion of liquid in shear bands despite increased porosity due to dilatancy. This apparent paradox is resolved by a microscale model for liquid transport at low liquid contents

Viscous shear banding in foam [PDF]
Physical Review E, 2008 Shear banding is an important feature of flow in complex fluids. Essentially, shear bands refer to the coexistence of flowing and nonflowing regions in driven material. Understanding the possible sources of shear banding has important implications for a wide range of flow applications.

Interface Instability in Shear-Banding Flow [PDF]
Physical Review Letters, 2006 We report on the spatio-temporal dynamics of the interface in shear-banding flow of a wormlike micellar system (cetyltrimethylammonium bromide and sodium nitrate in water) during a start-up experiment. Using the scattering properties of the induced structures, we demonstrate the existence of an instability of the interface between bands along the ...

Shear-banding instability in arbitrarily inelastic granular shear flows [PDF]
Physical Review E, 2019 One prototypical instability in granular flows is the shear-banding instability, in which a uniform granular shear flow breaks into alternating bands of dense and dilute clusters of particles having low and high shear (shear stress or shear rate), respectively.

A Study on the Law of Ring-Shear Band Evolution
Journal of Marine Science and Engineering, 2023 A separate-bottom Couette cell is used to carry out ring-shear tests on sand and hydrate, and the evolution of shear bands is recognized using the tracer method.

Coarse-grained description of localized inelastic deformation in amorphous metals [PDF]
, 2009 The sequence of shear transformation events that lead to a shear band transition in amorphous metals is described by a spatially random coarse-grained model calibrated to obey the thermodynamic scaling relations that govern flow in a real glass.

Micromechanics of shear banding [PDF]
Mechanics of Materials, 1994 Abstract Shear-banding is one of many instabilities observed during the plastic flow of solids. It is a consequence of the dislocation mechanism which makes plastic flow fundamentally inhomogeneous, and is exacerbated by local adiabatic heating.

Metals, 2021 In transformation-induced plasticity (TRIP) steel, the strain-induced martensitic transformation (SIMT) has a close relationship with the shear band formation.

Transient and steady-state shear banding in a lamellar phase as studied by Rheo-NMR [PDF]
, 2012 Flow fields and shear-induced structures in the lamellar (L-alpha) phase of the system triethylene glycol mono n-decyl ether (C10E3)/water were investigated by NMR velocimetry, diffusometry, and H-2 NMR spectroscopy. The transformation from multilamellar
