In this work, a study of the linear viscoelastic properties co-continuous polypropylene/polystyrene blends filled with multiwall carbon nanotubes (MWCNTs) is presented. The YZZ rheological model [W. Yu et al., Polymer 51, 2091–2098 (2010)] employed to correlate behavior their microstructure and electrical properties. A test design involving sequence small amplitude oscillatory shear time sweep ...

This review considers three general classes of physical as opposed to phenomenological models of the shear elasticity of tissues. The first is simple viscoelasticity. This model has a special role in elastography because it is the language in which experimental and clinical data are communicated. The second class of models involves acoustic relaxation, in which the medium contains inner time-de...

The rheology and shear-induced structures of a series of self-assembled surfactant worm-like micelles (WLMs) with varying levels of branching are measured using rheoand flow-small angle neutron scattering (SANS). The degree of branching in the mixed cationic/anionic surfactant (CTAT/SDBS) WLMs is controlled via the addition of the hydrotropic salt sodium tosylate and verified by cryo-TEM. The l...

We consider an integro-diierential equation which arises in linear viscoelasticity. By making use of an equivalent inner product, it is shown that the underlying contraction semigroup is exponentially stable. We also show that the nite dimensional semigroups arising from a known approximation scheme are uniformly exponentially stable.
