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.

Shear Bands in Matter with Granularity

Annual Review of Fluid Mechanics, 2010
Shear 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.

Shear strength and shear bands of anisotropic sand

Acta Geotechnica, 2021
Due to sedimentation, irregular particles of sand arrange anisotropically in nature. Anisotropy diversifies the internal friction angles between relative research planes at different directions in soil material. Thus, to analyze the mechanical mechanism of strength anisotropy, except for conventional inherent anisotropy of the material, stress ...

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.

Front Tracking for Shear Bands in an Antiplane Shear Model

Journal of Computational Physics, 1997
We describe a numerical algorithm for the study of shear band formation and growth in two-dimensional antiplane shear. The constitutive model uses a non-associative flow rule. The numerical scheme is based on a Godunov method for updating the velocity, while the stress is updated via integration along particle paths.

Shears band in the 105Sn nucleus

Zeitschrift für Physik A Hadrons and nuclei, 1997
The structure of 105Sn has been investigated through the 50Cr(58Ni,2pn) reaction at a beam energy of 210 MeV. In addition to an extension of the spherical level scheme, a regular sequence of dipole transitions has been found. The experimental results are in agreement with the prediction of Tilted Axis Cranking calculations, which satisfactorily explain

Shear bands in polycarbonate

Journal of Polymer Science: Polymer Physics Edition, 1973
AbstractLexan polycarbonate specimens in the form of tubes were deformed in torsion. The deformation occurs by the nucleation and growth of discrete shear bands. Shear bands are initially formed at the upper yield point. Development of the bands is accompanied by a drop in the stress to a lower yield point.
