Magnetic microrheometry of tumor-relevant stiffness levels and probabilistic quantification of viscoelasticity differences inside 3D cell culture matrices.

PLoS ONE, 2023
The progression of breast cancer involves cancer-cell invasions of extracellular matrices. To investigate the progression, 3D cell cultures are widely used along with different types of matrices.

Consolidation of Viscoelastic Soil With Vertical Drains for Continuous Drainage Boundary Conditions Incorporating a Fractional Derivative Model

Frontiers in Materials, 2021
In geotechnical engineering, vertical drainage is the most economical method for accelerating the consolidation of a large area of soft ground. In this study, we analyze the viscoelasticity of the soil and the actual drainage conditions on the top ...

Linear viscoelasticity of entangled wormlike micelles bridged by telechelic polymers : an experimental model for a double transient network [PDF]

, 2007
We survey the linear viscoelasticity of a new type of transient network: bridged wormlike micelles, whose structure has been characterized recently [Ramos and Ligoure, (2007)].

Viscoelastic properties of crystals [PDF]

The Journal of Chemical Physics, 2009
We examine the question of whether fluids and crystals are differentiated on the basis of their zero frequency shear moduli or their limiting zero frequency shear viscosity. We show that while fluids, in contrast with crystals, do have a zero value for their shear modulus, in contradiction to a widespread presumption, a crystal does not have an ...

Influence of viscoelasticity and interfacial slip on acoustic wave sensors [PDF]

, 2000
Acoustic wave devices with shear horizontal displacements, such as quartz crystal microbalances (QCM) and shear horizontally polarised surface acoustic wave (SH-SAW) devices provide sensitive probes of changes at solid-solid and solid- liquid interfaces.

Analysis of rolling on steel and rubber-covered rollers using viscoelasticity

Advances in Mechanical Engineering, 2019
In this article, a series of analysis were performed on a two-dimensional structure of steel and rubber-covered rollers. First, a hyperelastic–viscoelastic composite constitutive model based on a dynamic mechanical experiment of rubber was formulated to ...

Nonlinear viscoelasticity of metastable complex fluids

, 2006
Many metastable complex fluids such as colloidal glasses and gels show distinct nonlinear viscoelasticity with increasing oscillatory-strain amplitude; the storage modulus decreases monotonically as the strain amplitude increases whereas the loss modulus
