Shear-banding and microstructure of colloids in shear flow [PDF]

Faraday Discussions, 2002
We shall discuss the following phenomena found in various colloidal systems in shear flow. We recently observed shear-banding in suspensions of fd-virus in a cylindrical shear cell. Small angle light scattering experiments revealed that the shear-banding transition is preceded by a relatively fast process (minutes) of nematic-to-paranematic phase ...

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.

Structural mechanisms of formation of adiabatic shear bands [PDF]

Fracture and Structural Integrity, 2016
The paper focuses on the experimental and theoretical study of plastic deformation instability and localization in materials subjected to dynamic loading and high-velocity perforation.

Deformation-driven catalysis of nanocrystallization in amorphous Al alloys

Beilstein Journal of Nanotechnology, 2016
Nanocrystals develop in amorphous alloys usually during annealing treatments with growth- or nucleation-controlled mechanisms. An alternative processing route is intense deformation and nanocrystals have been shown to develop in shear bands during the ...

Deformation Microstructure And Texture Transformations In FCC Metals Of Medium-To-High Stacking Fault Energy: Critical Role Of Micro- And Macro-Scale Shear Bands

Archives of Metallurgy and Materials, 2015
Microstructure and texture development in medium-to-high stacking fault energy face centred cubic metals were investigated in order to examine the role of lattice re-orientation on slip propagation across grain boundaries and to characterize the ...

Athermal rheology of weakly attractive soft particles

, 2016
We study the rheology of a soft particulate system where the inter-particle interactions are weakly attractive. Using extensive molecular dynamics simulations, we scan across a wide range of packing fractions ($\phi$), attraction strengths ($u$) and ...

Shear bands in granular flow through a mixing length model [PDF]

, 2007
We discuss the advantages and results of using a mixing-length, compressible model to account for shear banding behaviour in granular flow. We formulate a general approach based on two function of the solid fraction to be determined.

Crossing of shears bands in 196Pb

Zeitschrift für Physik A Hadrons and Nuclei, 1996
High-spin states in 196Pb have been populated using the reaction 170Er(30Si,4n). The previously observed shears bands in this nucleus have been extended and some of their transitions have been reordered. They now form regular bands with band crossings. One of the bands splits into two pathways at high spin.

Shear band mediated microstructure in an accumulative roll bonded α-brass alloy during strain path changes and annealing

Journal of Materials Research and Technology
Strain path changes of the accumulative roll bonded 90Cu–10Zn brass and its influence on the shear band structure is the aim of the present study. The effect of post-annealing was also studied in terms of shear bands and texture development.

Morphologies of three-dimensional shear bands in granular media

, 2007
We present numerical results on spontaneous symmetry breaking strain localization in axisymmetric triaxial shear tests of granular materials. We simulated shear band formation using three-dimensional Distinct Element Method with spherical particles.
