Measuring the linear and nonlinear elastic properties of brain tissue with shear waves and inverse analysis
(Springer, 2015-02-20)
We use supersonic shear wave imaging (SSI) technique to measure not only the linear but also the nonlinear elastic properties of brain matter. Here, we tested six porcine brains ex vivo and measured the velocities of the ...
Gent models for the inflation of spherical balloons
(Elsevier, 2015)
We revisit an iconic deformation of non-linear elasticity: the inflation of a rubber spherical thin shell. We use the 3-parameter Mooney and Gent-Gent (GG) phenomenological models to explain the stretch-strain curve of a ...
Extreme softness of brain matter in simple shear
(Elsevier, 2015-03-13)
We show that porcine brain matter can be modelled accurately as a very soft rubber-like material using the Mooney-Rivlin strain energy function, up to strains as high as 60%. This result followed from simple shear experiments ...
Incremental equations for soft fibrous materials
(Springer, 2015)
The general theory of nonlinear anisotropic elasticity
is extended to describe small-amplitude motions and static deformations
that can be superimposed on large pre-strains of fibre-reinforced
solids. The linearised ...
Functional responses and adaptation of mesophilic microbial communities to psychrophilic anaerobic digestion
(Oxford University Press, 2015-10-27)
Psychrophilic (<20°C) anaerobic digestion (AD) represents an attractive alternative to mesophilic wastewater treatment. In order to investigate the AD microbiome response to temperature change, with particular emphasis on ...
