Transient Anomaly Imaging in Visco-Elastic Media Obeying a Frequency Power-Law [PDF]

, 2010
In this work, we consider the problem of reconstructing a small anomaly in a viscoelastic medium from wave-field measurements. We choose Szabo's model to describe the viscoelastic properties of the medium.

Measuring nanoscale viscoelastic parameters of cells directly from AFM force-displacement curves

Scientific Reports, 2017
Force-displacement (F-Z) curves are the most commonly used Atomic Force Microscopy (AFM) mode to measure the local, nanoscale elastic properties of soft materials like living cells.

Properties Tests and Mathematical Modeling of Viscoelastic Damper at Low Temperature With Fractional Order Derivative

Frontiers in Materials, 2019
In the present paper, several dynamic properties tests of the viscoelastic damper at −5°C are conducted under different frequencies and displacements to investigate the dynamic behavior of the viscoelastic damper at low temperature.

Viscoelastic Properties of Dynamically Asymmetric Binary Fluids Under Shear Flow [PDF]

, 2003
We study theoretically the viscoelastic properties of sheared binary fluids that have strong dynamical asymmetry between the two components. The dynamical asymmetry arises due to asymmetry between the viscoelastic stresses, particularly the bulk stress ...

Computational study on temperature-dependencies of relaxation and elastic properties in anisotropic viscoelastic constitutive law for fiber-reinforced thermoplastic resin

Nihon Kikai Gakkai ronbunshu, 2019
With use of the numerical material testing (NMT) approach based on homogenization theory, a time-temperature reduction law is proposed for both relaxation and elastic properties in the orthotropic viscoelastic constitutive equation, which is supposed to ...

Viscoelastic properties of epithelial cells

Biochemical Society Transactions, 2021
Epithelial cells form tight barriers that line both the outer and inner surfaces of organs and cavities and therefore face diverse environmental challenges. The response to these challenges relies on the cells’ dynamic viscoelastic properties, playing a pivotal role in many biological processes such as adhesion, growth, differentiation, and motility ...

Chemical control of the viscoelastic properties of vinylogous urethane vitrimers

Nature Communications, 2017
Vinylogous urethane based vitrimers are polymer networks that have the intrinsic property to undergo network rearrangements, stress relaxation and viscoelastic flow, mediated by rapid addition/elimination reactions of free chain end amines.

The coexistence of pressure waves in the operation of quartz-crystal shear-wave sensors [PDF]

, 1998
It is demonstrated that an AT-cut quartz crystal driven in the thickness-shear-wave mode and typically used as a sensor to monitor the viscoelastic shear-wave properties of a fluid also produce longitudinal pressure waves.
