Effects of viscosity and refractive index on the emission and diffusion properties of Alexa Fluor 405 using fluorescence correlation and lifetime spectroscopies
(Springer, 2021-03-19)
Fluorescence Correlation Spectroscopy (FCS) studies of the interaction of polymers or proteins in solution are strongly affected by the viscosity and refractive index of the medium, and the effects are likely to be more ...
Singular travelling waves in soft viscoelastic solids of rate type
(Elsevier, 2023-09-25)
We consider shear wave propagation in soft viscoelastic solids of rate type. Based on objective stress rates, the constitutive model accounts for finite strain, incompressibility, as well as stress- and strain-rate ...
Programmable wrinkling for functionally-graded auxetic circular membranes
(Elsevier, 2023-07-13)
Materials with negative Poisson¿s ratio, also known as auxetic materials, display exotic properties such
as expansion in all directions under uni-axial tension. For their unique properties, these materials find
a broad ...
Stochastic modelling of pesticide transport to drinking water sources via runoff and resulting human health risk assessment
(Elsevier, 2024-02-09)
A modelling framework was developed to facilitate a probabilistic assessment of health risks posed by pesticide exposure via drinking water due to runoff, with the inclusion of influential site conditions and in-stream ...
Representing the stress and strain energy of elastic solids with initial stress and transverse texture anisotropy.
(The Royal Society, 2022-10-12)
Real-world solids, such as rocks, soft tissues and engineering materials, are often under some form of stress. Most real materials are also, to some degree, anisotropic due to their microstructure, a characteristic often ...
Modelling brain tissue elasticity with the Ogden model and an alternative family of constitutive models.
(The Royal Society, 2022-08-29)
The Ogden model is often considered as a standard model in the literature for application to the deformation of brain tissue. Here, we show that, in some of those applications, the use of the Ogden model leads to the ...
The Ogden model of rubber mechanics: 50 years of impact on nonlinear elasticity
(The Royal Society, 2022-08-29)
We place the Ogden model of rubber elasticity, published in Proceedings of the Royal Society 50 years ago, in the wider context of the theory of nonlinear
elasticity. We then follow with a short interview of Ray Ogden FRS ...
Acousto-elasticity of transversely isotropic incompressible soft tissues: Characterization of skeletal striated muscle
(IOP Publishing, 2021-07-13)
Using shear wave elastography, we measure the changes in the wave speed with the stress produced by a striated muscle during isometric voluntary contraction. To isolate the behaviour of an individual muscle from complementary ...
A hyperbolic framework for shear sound beams in nonlinear solids
(Elsevier, 2021-09-14)
In soft elastic solids, directional shear waves are in general governed by coupled nonlinear KZK-type equations for the two transverse velocity components, when both quadratic nonlinearity and cubic nonlinearity are taken ...
Nonlinear vibration and stability of a dielectric elastomer balloon based on a strain-stiffening model
(Springer, 2022-05-23)
Limiting chain extensibility is a characteristic that plays a vital role in the stretching of highly elastic materials. The Gent model has been widely used to capture this behaviour, as it performs very well in fitting ...
