Effect of PMMA polymer on the dynamic viscoelasticity and plasticizer leachability of PEMA-based tissue conditioners [PDF]

open access: yes, 2010
The purpose of this study was to determine the effect of PMMA polymer on dynamic viscoelasticity and plasticizer leachability of PEMA-based tissue conditioners. One PEMA polymer and one PMMA polymer were used in powder form with four formulations.

A Viscoelastic Catastrophe

open access: yesCoRR, 2018
We use a differential constitutive equation to model the flow of a viscoelastic flow in a cross-slot geometry, which is known to exhibit bistability above a critical flow rate. The novelty lies in two asymmetric modifications to the geometry, which causes a change in the bifurcation diagram such that one of the stable solutions becomes disconnected ...

Viscoelasticity, Like Forces, Plays a Role in Mechanotransduction

open access: yesFrontiers in Cell and Developmental Biology, 2022
Viscoelasticity and its alteration in time and space has turned out to act as a key element in fundamental biological processes in living systems, such as morphogenesis and motility.

On necessary precautions when measuring solid polymer linear viscoelasticity with dynamic analysis in torsion [PDF]

open access: yes, 2017
Solid polymer linear viscoelasticity in shear is often characterized by applying torsion and using the Saint-Venant solution when rectangular prismatic specimens are considered.

Membrane viscoelasticity

open access: yesBiophysical Journal, 1976
In this paper, we develop a theory for viscoelastic behavior of large membrane deformations and apply the analysis to the relaxation of projections produced by small micropipette aspiration of red cell discocytes. We show that this relaxation is dominated by the membrane viscosity and that the cytoplasmic and extracellular fluid flow have negligible ...

Viscoelasticity Measurement and Identification of Viscoelastic Parametric Models

open access: yesVolume 1: 23rd Biennial Conference on Mechanical Vibration and Noise, Parts A and B, 2011
Generally speaking, the behaviour of viscoelastic material is more complicated than the behaviour proposed by classical models as Voigt, Maxwell or Zener. The stiffness of such materials is a frequency dependent complex function. Above 1000Hz, classical measurements techniques are unable to achieve accurate measurements of the stiffness. In this paper,
