Microstructure and formation mechanisms of nanotwins in the shear band in a FeCoNiCrMo0.2 high-entropy alloy

open access: yesJournal of Materials Research and Technology, 2022
High-entropy alloys (HEAs) containing nanotwins exhibit simultaneous high strength and great plasticity. The instantaneous formation mechanism of nanotwins in a shear band in the hot-extruded FeCoNiCrMo0.2 HEA has been investigated.

Viscous shear banding in foam [PDF]

open access: yesPhysical 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.

Study on Physical and Mechanical Characteristics of Shear Band in Jinpingzi Landslide Region II

open access: yesFrontiers in Physics, 2022
The shear band is an important portion of a landslide. Investigating the shear band’s physical characteristics is one of the most significant challenges for landslide stability analysis and control. A systematic study of shear band in Jinpingzi landslide

Interface Instability in Shear-Banding Flow [PDF]

open access: yesPhysical 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]

open access: yesPhysical 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

open access: yesJournal 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]

open access: yes, 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]

open access: yesMechanics 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.

A Crystal Plasticity Simulation on Strain-Induced Martensitic Transformation in Crystalline TRIP Steel by Coupling with Cellular Automata

open access: yesMetals, 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]

open access: yes, 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
