Compactive shear bands

, 2020
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).

Mapping Shear Bands in Metallic Glasses: From Atomic Structure to Bulk Dynamics.

Physical Review Letters, 2022
A deep understanding of the mechanisms controlling shear banding is of fundamental importance for improving the mechanical properties of metallic glasses. Atomistic simulations highlight the importance of nanoscale stresses and strains for shear banding,

FRACTAL PLASTIC SHEAR BANDS

Fractals, 1994
We present a numerical study model of shear bands in rocks with a non-associated plastic flow rule. The system drives spontaneously into a state in which the length distribution of shear bands follows a power law and where the spatial organization of the shear bands appears to be fractal.

Dynamic shear band propagation and micro-structure of adiabatic shear band

Computer Methods in Applied Mechanics and Engineering, 2001
A meshfree Galerkin approximation, reproducing kernel particle method, is used in the displacement-based explicit formulation to simulate dynamic shear band propagation as well as microstructures of adiabatic shear bands. The main advantages of using meshfree interpolants are two: (i) it can effectively avoid mesh-alignment sensitivity that finite ...

Reverse shearing of shear bands in polystyrene

Journal of Materials Science, 1982
Shear bands produced in polystyrene by compression can be reverse sheared by a second compression in a perpendicular direction. The net shear strain can be zero or negative. Like the forward shear, the reverse shear also produces a ridge on the surface. The height of the ridge seems to be proportional to the reverse shear strain.
