Stress correlations in glasses
Anaël Lemaître
We rigorously establish that, in disordered three-dimensional (3D) isotropic solids, the stress autocorrelation function presents anisotropic terms that decay as at long-ra…
Rheology and microstructure of unsaturated granular materials: Experiments and simulations
M. Badetti, A. Fall, F. Chevoir +3
When dealing with unsaturated wet granular materials, a fundamental question is: what is the effect of capillary cohesion on the bulk flow and yield behavior? We inwestigate the de…
Shear strength of wet granular materials: macroscopic cohesion and effective stress
Michel Badetti, Abdoulaye Fall, François Chevoir +1
Rheometric measurements on assemblies of wet polystyrene bead assemblies, in steady uniform quasistatic shear flow, for varying liquid content within the small saturation (pendular…
Stochastic homogenization of a scalar viscoelastic model exhibiting stress-strain hysteresis
Thomas Hudson, Frédéric Legoll, Tony Lelièvre
Motivated by rate-independent stress-strain hysteresis observed in filled rubber, this article considers a scalar viscoelastic model in which the constitutive law is random and var…
