Nature of ductile shear banding under shock loading
Micro & 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.

Applied 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.

Metals, 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 ...

High Explosive Ignition through Chemically Activated Nanoscale Shear Bands.
Physical Review Letters, 2020 Shock initiation and detonation of high explosives is considered to be controlled through hot spots, which are local regions of elevated temperature that accelerate chemical reactions.

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

Journal 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 ...

Evolution of cracks in the shear bands of granite residual soil
Journal of Rock Mechanics and Geotechnical Engineering, 2022 The evolution of shear bands and cracks plays an important role in landslides. However, there is no systematic method for classification of the cracks, which can be used to analyze the evolution of cracks in shear bands.

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 ...
