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).

Shear bands appear at limit states of soil bodies. They are analysed as thin zones of localised deformation that takes place as simple (i.e. dilatant) shear. It can be observed, however, that shear bands are discontinuous and also may be “reflected” at rigid boundaries. These phenomena appear as incompatible with the assumed shear deformation.

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).

Shear Bands in Matter with Granularity
Annual Review of Fluid Mechanics, 2010Shear bands, localized regions where shear flows concentrate, form in many complex fluids under a wide range of circumstances. In this review, we outline the main mechanisms that cause shear banding in complex fluids with granularity: foams, emulsions, colloidal suspensions, and granular matter.

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 Band Patterns in Biaxially Sheared Granular Media
AIP Conference Proceedings, 2009Applying the principle of least dissipation rate to the biaxial shear geometry leads to the prediction that there are preferred shear band patterns according to the aspect ratio of the shear cell. By means of the Mohr‐Coulomb angle these patterns can be classified in terms of two integer indices.

Multiple Shear Banding in Granular Materials
2013We present numerical and experimental evidences for multiple shear band formation in sheared granular materials. A modified Couette cell with a split bottom near the outer cylinder is made rough by gluing glass beads on all boundaries. The cell is filled with the same beads and sheared by slowly rotating the inner cylinder and the attached bottom disk.
