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.

Recrystallization Behavior of Warm Rolling and Cold Rolling Cr-Ti-B Steel during Annealing
Metals, 2022 To study the nucleation and recrystallization behavior of deformation bands, shear bands and grain boundaries during the recrystallization process, a heat treatment test was carried out on Cr-Ti-B low-carbon steel after warm rolling and cold rolling. The

The Stress-Force-Fabric relation across shear bands [PDF]
EPJ Web of ConferencesThe strength of granular materials is highly dependent on grain connectivity (fabric), force transmission, and frictional mobilization at the particle scale. Furthermore, these bulk properties are strongly dependent on the geometry and history of loading.

Non-linear oscillatory rheological properties of a generic continuum foam model: comparison with experiments and shear-banding predictions [PDF]
, 2012 The occurence of shear bands in a complex fluid is generally understood as resulting from a structural evolution of the material under shear, which leads (from a theoretical perspective) to a non-monotonic stationnary flow curve related to the ...

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.

Formation of Micro Shear Bands During Severe Plastic Deformation of BCC Alloys [PDF]
Journal of Stress Analysis, 2018 In this work, tendencies of pure Niobium, Fe-20Cr stainless steel, and Ti-36Nb-2Ta-3Zr to formation of micro shear bands inside their microstructures during severe plastic deformation are compared with their mechanical properties.

Visualization technology and application analysis of shearing tests for different kinds of soil
Shenzhen Daxue xuebao. Ligong ban, 2023 In order to study the application of visualization technology in shear tests of soil and the deformation mechanism of shear band, shearing tests on different kinds of soil are carried out by using the visualization shear equipment. Combining with digital

Multiple shear bands in granular materials
EPJ Web of Conferences, 2017 The transition regime from quasi-static to dynamic shear regime is studied by discrete element method (DEM) and by means of a mesoscopic model. We show that at moderate shear rate multiple shear bands appear which eventually appear as a continuous shear ...

Investigation of shear band strengthening by using different strengthening criteria [PDF]
E3S Web of ConferencesTo prevent a critical failure mechanism, it is possible to simply strengthen the potential shear bands, which is a patented idea. The localization of potential shear bands that are most likely to form shear can be calculated. Before these shear bands can

Rate dependent shear bands in a shear transformation zone model of amorphous solids [PDF]
, 2008 We use Shear Transformation Zone (STZ) theory to develop a deformation map for amorphous solids as a function of the imposed shear rate and initial material preparation.
