Shear-band toughness of bulk metallic glasses
Acta Materialia, 2011 Dynamic "forced" shear and quasi-static tensile tests were performed on a typical Vitreloy 1 bulk metallic glass (BMG). The nanoscale shear band is found to initiate in a local plastic region, then propagates with a well-defined front.

Prediction of shear-band thickness in metallic glasses
Scripta Materialia, 2009 We derive an explicit expression for predicting the thicknesses of shear bands in metallic glasses. The model demonstrates that the shear-band thickness is mainly dominated by the activation size of the shear transformation zone (STZ) and its activation ...

Is a birefringence band a shear band?
Europhysics Letters (EPL), 2000The discrepancy between the width of birefringence bands and shear rate bands in the system CTAB/water is addressed using a combination of NMR spectroscopy and NMR velocimetry. In correspondence with birefringence measurements in the annular gap of a cylindrical Couette cell, 2H NMR spectroscopy indicates a separation of fluid into distinct nematic and

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, 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.

Shear strength and shear bands of anisotropic sand
Acta Geotechnica, 2021Due 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, 1982Shear 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.
