Anomalous lateral diffusion in a viscous membrane surrounded by viscoelastic media

, 2012
We investigate the lateral dynamics in a purely viscous lipid membrane surrounded by viscoelastic media such as polymeric solutions. We first obtain the generalized frequency-dependent mobility tensor and focus on the case when the solvent is sandwiched ...

STRUCTURE AND DYNAMICS OF IRREGULAR MULTIARM STAR POLYMERS

Condensed Matter Physics, 2002
Melt properties of highly branched star polymers consisting of a 1,2-polybutadiene core and nearly 270 arms of 1,4-polybutadiene with varying sizes have been investigated using small angle X-ray scattering (SAXS) and dynamic rheological measurements in ...

Milligram Size Rheology of Molten Polymers

Fluids, 2019
During laboratory practice, it is often necessary to perform rheological measurements with small specimens, mainly due to the limited availability of the investigated systems.

Characterization of Asphalt Mixes Behaviour from Dynamic Tests and Comparison with Conventional Cyclic Tension–Compression Tests

Applied Sciences, 2018
In the presented research, conventional cyclic tension⁻compression tests and dynamic tests were performed on two types of asphalt mixes (AM). For the tension⁻compression tests, the complex modulus was obtained from the measurements of the ...

Modeling Viscoelastic Behavior of HDPE Pipes Subjected to a Diametral Load Using the Standard Linear Solid Model

Modelling
This paper presents the study of the viscoelastic behavior of high-density polyethylene (HDPE) ASTM 4710 pipes under diametral loads. The experimental procedure consists of applying a displacement ramp followed by a stress relaxation stage on six ring ...

A variant of the energy method: an application to the Benard problem for a viscoelastic rotating fluid

Atti della Accademia Peloritana dei Pericolanti : Classe di Scienze Fisiche, Matematiche e Naturali, 2019
In a previous paper of the second author the nonlinear Lyapunov stability of the thermodiffusive equilibrium of a viscoelastic rotating Walters fluid, in a horizontal rotating layer heated and salted from below was studied.
