Shear bands in dense fault gouge [PDF]

open access: yesEPJ Web of Conferences, 2021
Earthquakes happen with frictional sliding, by releasing all the stresses accumulated in the prestressed surrounding medium. The geological fault gouge, coming from the wear of previous slips, acts on friction stability and plays a key role in this ...

Shearing of granular materials in a confined split-bottom Couette cell [PDF]

open access: yesEPJ Web of Conferences, 2021
Formation of shear bands is one of the most remarkable phenomena in the dynamics of granular matter. Several parameters have been so far identified to influence the behavior of the shear bands.

Twin-coupled shear bands in an ultrafine-grained CoCrFeMnNi high-entropy alloy deformed at 77K

open access: yesMaterials Research Letters, 2022
Two different types of shear bands generate in ultrafine-grained (UFG) CoCrFeMnNi high-entropy alloys deformed at 77 K, i.e. commonly-observed low angle grain boundary (LAGB) type and unusual twin-coupled type.

Fluid Depletion in Shear Bands [PDF]

open access: yesPhysical 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

Nature of ductile shear banding under shock loading

open access: yesMicro & Nano Letters, 2021
Under shock loading, the plastic flow of polycrystalline material tends to localise into shear bands. As shear bands form, most materials dramatically lose their strain hardening property and quickly fail.

Evolution of Shear Band in Plane Strain Compression of Naturally Structured Clay with a High Sensitivity

open access: yesApplied Sciences, 2022
The formation of the shear band is associated with the failure of soil. However, there has been relatively little investigation on the evolution of shear bands in naturally structured clay with a high sensitivity.

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

open access: yesFaraday 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 ...

In Situ Generated Shear Bands in Metallic Glass Investigated by Atomic Force and Analytical Transmission Electron Microscopy

open access: yesMetals, 2022
Plastic deformation of metallic glasses performed at temperatures well below the glass transition proceeds via the formation of shear bands. In this contribution, we investigated shear bands originating from in situ tensile tests of Al88Y7Fe5 melt-spun ...

Shear bands of as-cast and semi-solid Ti48Zr27Cu6Nb5Be14 bulk metallic glass matrix composites [PDF]

open access: yesChina Foundry, 2021
The as-cast Ti48Zr27Cu6Nb5Be14 bulk metallic glass matrix composites (BMGMCs) were fabricated using a copper mold suction casting method. Then, the semi-solid BMGMC samples were obtained following an isothermal treatment (heating at 900 °C for 10 min ...

Size dependence of ductile to brittle transition of Zr-based metallic glasses under multiaxial loading

open access: yesJournal of Materials Research and Technology, 2021
The size dependence of ductile to brittle transition of Zr-based metallic glasses was systematically investigated by small punch test. It was found that the metallic glasses with thickness ranging from 50 to 700 μm displayed an obvious transition from ...
