Phenomenology and physical origin of shear localization and shear banding in complex fluids [PDF]
Rheologica Acta, 2009 We review and compare the phenomenological aspects and physical origin of shear-localization and shear-banding in various material types, namely emulsions, suspensions, colloids, granular materials and micellar systems. It appears that shear-banding, which must be distinguished from the simple effect of coexisting static-flowing regions in yield stress

Deformation lines in Arctic sea ice: intersection angle distribution and mechanical properties [PDF]
The Cryosphere, 2023 Despite its relevance for the Arctic climate and ecosystem, modeling sea-ice deformation, i.e., the opening, shearing, and ridging of sea ice, along linear kinematic features (LKFs) remains challenging, as the mechanical properties of sea ice are not ...

Physical origin of shear-banding in jammed systems [PDF]
The European Physical Journal E, 2010 Jammed systems all have a yield stress. Among these materials some have been shown to shear-band but it is as yet unclear why some materials develop shear-band and some others do not. In order to rationalize existing data concerning the flow characteristics of jammed systems and in particular understand the physical origin of such a difference we ...

Deep Underground Science and Engineering, 2023 Frictional stick–slip instability along pre‐existing faults has been accepted as the main mechanism of earthquakes for about 60 years, since it is believed that fracture of intact rocks cannot reflect such features inherent in earthquakes as low shear ...

New physics of supersonic ruptures
Deep Underground Science and Engineering, 2023 Until recently, it is believed that the rupture speed above the pressure wave is impossible since spontaneously propagating ruptures are driven by the energy released due to the rupture motion, which is transferred through the medium to the rupture tip ...

Rortex and comparison with eigenvalue-based vortex identification criteria [PDF]
The Physics of Fluids, 2018 Most of the currently popular Eulerian vortex identification criteria, including the Q criterion, the Delta criterion and the Lambda_ci criterion, are based on the analysis of the velocity gradient tensor.

Investigation of the physical mechanisms of shear-force imaging [PDF]
Journal of Applied Physics, 1996 It is shown that shear-force imaging, as is commonly used for distance regulation in scanning near-field optical microscopy, is not a reliable technique for accurate topographic measurements. This is because different materials experience different shear-force damping.

Critical scaling of shearing rheology at the jamming transition of soft-core frictionless disks. [PDF]
Physical review. E, Statistical, nonlinear, and soft matter physics, 2010 We perform numerical simulations to determine the shear stress and pressure of steady-state shear flow in a soft-disk model in two dimensions at zero temperature in the vicinity of the jamming transition ϕ{J}.
