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 ...
The generalised Mooney space for modelling the response of rubber-like materials
(Springer, 2022-03-23)
Soft materials such as rubbers, silicones, gels and biological tissues have a nonlinear response to large deformations, a phenomenon which in principle can be captured by hyperelastic models. The suitability of a candidate ...
Plane-polarised finite-amplitude shear waves in deformed incompressible materials
(SAGE Publications, 2022-04-07)
We investigate how two finite-amplitude, transverse, plane body waves may be superposed to propagate in a deformed hyperelastic incompressible solid. We find that the equations of motion reduce to a well-determined system ...
Canceling the elastic Poynting effect with geometry
(American Physical Society, 2023-05-24)
The Poynting effect is a paragon of nonlinear soft matter mechanics. It is the tendency (found in all incompressible, isotropic, hyperelastic solids) exhibited by a soft block to expand vertically when sheared horizontally. ...
Global perspectives on operational excellence: unveiling critical failure factors and sustainable pathways
(Emerald, 2024-03-14)
Purpose
The purpose of this global study is to investigate the critical failure factors (CFFs) in the deployment of operational excellence (OPEX) programs as well as the key performance indicators (KPIs) that can be used ...
How do organizational performances vary between early adopters and late adopters of Quality 4.0? An exploratory qualitative study
(Emerald, 2023-08-24)
This study aims to investigate how early and late adopters of Q4.0 differ in terms of organizational performance.
The authors employed a grounded theory approach for interviewing 15 senior managers from diverse organizational ...
