On the Stability of Shear Bands
1995Prediction of the onset of localization of the deformation in solids under stress, and, in particular, the initiation of shear bands, is a problem of considerable importance in the context of metal plasticity (see, for example, the review by Rice [1]).

Dilatant shear bands in solidifying metals
Nature, 2007Compacted granular materials expand in response to shear, and can exhibit different behaviour from that of the solids, liquids and gases of which they are composed. Application of the physics of granular materials has increased the understanding of avalanches, geological faults, flow in hoppers and silos, and soil mechanics.

Shear Banding in an F-Actin Solution
Physical Review Letters, 2012We report herein the first evidence that an F-actin solution shows shear banding, which is characterized by the spontaneous separation of homogeneous shear flow into two macroscopic domains of different definite shear rates. The constant shear stress observed in the F-actin solution is explained by the banded flow with volume fractions that obey the ...

Physics Letters A, 1986
Abstract One mechanism for ignition of propellants and explosives involves shear banding, in which the healing due to visco-plastic effects combines with the reactive heating to reduce the critical size. To study this process, the analysis of Frank-Kamenetskii is generalized herein to account for mechanical effects (shear).

High-porosity arkose sandstones of Loiano (LS; Northern Apennines, Italy) are medium to coarse-grained and composed by quartz, feldspar, rock fragments, a few carbonate clasts, and minor accessories. LS are an example of structural-controlled diagenesis, because of the presence of calcite-cement nodules associated to the deformation bands (DBs).

On the Shear Bands and Shear Localizations in EHL Films
ASME/STLE 2004 International Joint Tribology Conference, Parts A and B, 2004Liquid lubricants in elastohydrodynamic lubrication (EHL) are subjected to high pressures of the magnitude of 109 N/m2 (GPa). Under these high pressures, the lubricants in room temperatures are usually in the glassy state behaving as amorphous solids.
