Shear Banding in 4:1 Planar Contraction [PDF]

open access: yesPolymers, 2019
We study shear banding in a planar 4:1 contraction flow using our recently developed two-fluid model for semidilute entangled polymer solutions derived from the generalized bracket approach of nonequilibrium thermodynamics. In our model, the differential

On the origin of shear banding instability in metallic glasses

open access: yesJournal of the Mechanics and Physics of Solids, 2009
To uncover the physical origin of shear-banding instability in metallic glass (MG), a theoretical description of thermo-mechanical deformation of MG undergoing one-dimensional simple shearing is presented.

Onset and Direction of Shear Banding Instability in Metallic Glasses

open access: yesJournal of Materials Science and Technology, 2014
The shear banding instability occurs as the homogenous deformation in metallic glasses (MGs) develops to a critical point, at which the discontinuity in deformation rate is incipient across nano-scale shear bands.

Is a birefringence band a shear band?

Europhysics Letters (EPL), 2000
The 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

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 ...
