We consider the anti-plane shear waves in a domain consisting of an infinite layer with thin coating lying on elastic half-space. The properties coating, layer, and half-space are assumed to be different. On free upper surface we assume compatibility condition within Gurtin–Murdoch elasticity, whereas at plane interface perfect contact. For this problem there exist two possible regimes related ...

Title of dissertation: ONSET OF GRANULAR FLOWS BY LOCAL AND GLOBAL FORCING Masahiro Toiya, Doctor of Philosophy, 2006 Dissertation directed by: Professor Wolfgang Losert Department of Physics, Institute for Research in Electronics and Applied Physics and Institute for Physical Sciences and Technology This thesis focuses on the onset of granular flows and memory effects in granular materials und...

Heterogeneity of granular materials triggers shear zone formation. In the paper, the FE-analysis of the effect of the material heterogeneity on the formation of a spontaneous shear zone inside of granular materials during a plane strain compression test is presented. The numerical calculations are performed with a finite element method on the basis of a hypoplastic constitutive law extended by ...

2014 Glycerol mono-oleate monolayers at the air-water interface have been investigated by quasielastic light scattering from thermally excited capillary waves over a wide range of wave numbers. Using a relatively novel data analysis procedure four surface viscoelastic properties were deduced ab initio from the light scattering data : surface elastic moduli and viscosities governing shear normal...

Abstract This paper aims to develop the nonlinear incremental modeling approach for describing both monotonic and cyclic behaviors of soil‐structure interface. An exponential function is adopted as an example reproduce asymptotic relationship between interface shear stress ratio displacement. A stress‐dilatancy relation developed shear‐induced change thickness. reversal technique incorporated l...

The shear-transformation-zone (STZ) theory has been remarkably successful in accounting for broadly peaked, frequency-dependent, viscoelastic responses of amorphous systems near their glass temperatures T_{g}. This success is based on the theory's first-principles prediction of a wide range of internal STZ transition rates. Here, I show that the STZ rate distribution causes the Newtonian viscos...

Abstract The kinematics and the shear-induced alignment of elongated particles in confined, heterogeneous flow conditions are investigated experimentally. Experiments conducted an annular shear cell with a rotating bottom wall top permitting confinement flow. Flow particle orientation statistics computed by tracking using optical imaging. Translational velocity profiles show exponential decay, ...

We investigate the effects of fluid elasticity on the dynamics of filament thinning and drop breakup processes in a cross-slot microchannel. Elasticity effects are examined using dilute aqueous polymeric solutions of molecular weight (MW) ranging from 1.5×103 to 1.8×107. Results for polymeric fluids are compared to those for a viscous Newtonian fluid. The shearing or continuous phase that induc...
