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 ...
Waves and vibrations in a solid of second grade
(World Scientific, 2006)
We study the viscoelastic second grade solid, for which the constitutive equation
consists in the sum of a purely elastic part and a viscoelastic part; this latter part
is specified by two microstructural coefficients ...
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 ...
A note about waves in dissipative and dispersive solids
(World Scientific, 2008)
We study shear waves propagating in a special viscoelastic model proposed first by
Fosdick and Yu in 1996. We deduce an asymptotic approximation which reduces
the full balance equations to a system of evolution equations ...
Interface waves in pre-stressed incompressible solids
(Springer, 2007)
We study incremental wave propagation for what is seemingly the simplest boundary value problem, namely that constitued by the plane interface of a semi-infinite solid. With a view to model loaded elastomers and soft ...
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 ...
Mechanical properties of excised human skin
(Springer Verlag, 2010)
In this study we have investigated in influence of
location, gender and orientation on the deformation characteristics
of 55 samples of human excised skin. Uniaxial tensile
tests were carried out at a strain rate of ...
John Todd and the development of modern numerical analysis
(2012)
The purpose of this article is to mark the centenary of the birth of
John Todd, a pioneer in the fields of numerical analysis and computational
science. A brief account is given of his early life and career, and that
of ...
On the complexity of multiplication in the Iwahori-Hecke algebra of the symmetric group
(Elsevier, 2016-09-12)
We present new efficient data structures for elements of Coxeter groups of type Am and their associated Iwahori Hecke algebras H(A(m)). Usually, elements of H(A(m)) are represented as simple coefficient list of length M = ...
