We attribute similarities in the rheology of many soft materials (foams, emulsions, slurries, etc.) to the shared features of structural disorder and metastability. A generic model for the mesoscopic dynamics of ``soft glassy matter'' is introduced, with interactions represented by a mean-field noise temperature $x$. We find power-law fluid behavior either with $(xl1)$ or without $(1lxl2)$ a yield stress. For $1lxl2$, both storage and loss modulus vary with frequency as ${\ensuremath{\omega…

Rheological Properties of Liquids Under Conditions of Elastohydrodynamic Lubrication
There is an ongoing debate concerning the best rheological model for liquid flows in elastohydrodynamic lubrication (EHL). Due to the small contact area and high relative velocities of bounding

This paper generalizes the study of the heterogeneous dynamics of glassy materials to the finite shear rate and temperature case and finds that the model Lennard-Jones glass follows the rheological behavior of a yield stress fluid with a Herschel-Bulkley response of the form.
We review models for the rheology of soft glasses, a class of materials including e.g. emulsions, foams, colloidal glasses and possibly—but with substantial caveats—gels. The main focus is on the
Soft glassy rheology model applied to stress relaxation of a thermoreversible colloidal gel
Measurements of the stress relaxation modulus of a thermoreversible colloidal gel are compared with the predictions of the soft glassy rheology (SGR) model of Sollich and co-workers [Sollich et al.,
Protocol-dependent shear modulus of amorphous solids
We investigate the linear elastic response of amorphous solids to a shear strain at zero temperature. We find that the response is characterized by at least two distinct shear moduli. The first one,
Dynamics and Rheology of Soft Colloidal Glasses
The linear viscoelastic (LVE) spectrum of a soft colloidal glass is accessed with the aid of a time-concentration superposition (TCS) principle, which unveils the glassy particle dynamics from

The proposed framework provides an operational way to distinguish between 'soft' glasses and 'hard' glasses based on the shear-rate dependence of the structural relaxation time, and is able to describe all key features of deformation of 'hard', including the yielding transition, the nonaffine-to-affine plateau crossover, and the rate-stiffening of the modulus.

By integrating out nonessential, harmonic degrees of freedom, a simplified scalar version of the model is derived that represents a collection of interacting Prandtl-Tomlinson particles and observes the value of β to depend on some details of the plastic disorder potential.
Ageing, driving and effective temperatures from soft rheology" to glassy dynamics "
This thesis studies non-equilibrium dynamics in disordered "glassy" systems, focusing particularly on the response of such systems to external driving and loading. Its primary motivation is a body of
After a brief`warm-up' discussion of osmotic pressure of foams, the basic phenomena of foam rheology are reviewed, focusing on linear vis-coelastic spectra (elastic and loss moduli) with brief

Strain is the response to the stress of liquids, solids and substances in between the former two that if a stress is applied to them, they will strain.
