Rheology of Soft Glassy Materials
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 sx , 1d or without s1 , x , 2d a yiel...
متن کاملNonequilibrium thermodynamics and glassy rheology
Mechanically driven glassy systems and complex fluids exhibit a wealth of rheological behaviors that call for theoretical understanding and predictive modeling. A distinct feature of these nonequilibrium systems is their dynamically evolving state of structural disorder, which determines their rheological responses. Here we highlight a recently developed nonequilibrium thermodynamic framework i...
متن کاملRheology and Glassy Dynamics of Foams
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 mention of nonlinear eeects. Theoretical models for some of these properties are then described, starting with Princen's model for the elastic modulus G 0 of an ordered foam in two dimensions. There is a ...
متن کاملSoft glassy rheology of supercooled molecular liquids.
We probe the mechanical response of two supercooled liquids, glycerol and ortho-terphenyl, by conducting rheological experiments at very weak stresses. We find a complex fluid behavior suggesting the gradual emergence of an extended, delicate solid-like network in both materials in the supercooled state-i.e., above the glass transition. This network stiffens as it ages, and very early in this p...
متن کاملOn the cytoskeleton and soft glassy rheology.
The cytoskeleton is a complex structure within the cellular corpus that is responsible for the main structural properties and motilities of cells. A wide range of models have been utilized to understand cytoskeletal rheology and mechanics (see e.g. [Mofrad, M., Kamm, R., 2006. Cytoskeletal Mechanics: Models and Measurements. Cambridge University Press, Cambridge]). From this large collection of...
