Abstract:
Instability of the structure of viscous fluids in the Couette flow regime (spontaneous formation of bands, which are tangential discontinuities in terms of viscosity) is experimentally found. This process is demonstrated to be analogous to formation of shear bands in polymethylmethacrylate (Plexiglas) under plastic shear strains.
Keywords:
structural viscosity of fluids, shear strains, instability of the structure.
