Piezoelectric Love waves on rotated Y-cut mm2 substrates
(IEEE, 2006-11)
Consider a layer consisting of a m3m dielectric crystal, with faces cut parallel to a symmetry plane. Then bond it onto a semi-infinite mm2 piezoelectric substrate. For an X- or Y-cut of the substrate, a Love wave can ...
Instabilities in elastomers and soft tissues
(Oxford Journals, 2006-09-15)
Biological soft tissues exhibit elastic properties that can be dramatically different from rubber-type materials (elastomers). To gain a better understanding of the role of constitutive relationships in determining material ...
The speed of interfacial waves polarized in a symmetry plane
(Elsevier, 2006-01)
The surface-impedance matrix method is used to study interfacial waves polarized in a plane of symmetry of anisotropic elastic materials. Although the corresponding Stroh polynomial is a quartic, it turns out to be ...
Weierstrass's criterion and compact solitary waves
(American Physical Society, 2007-04-17)
Weierstrass's theory is a standard qualitative tool for single degree of freedom equations, used in classical mechanics and in many textbooks. In this Brief Report we show how a simple generalization of this tool makes it ...
Finite-amplitude Love waves in a pre-stressed neo-Hookean material
(2008)
In the context of the non-linear elasticity theory we consider a model for compressible solids called compressible neoHookean
material . We show how (exact) finite-amplitude inhomogeneous plane wave solutions and ...
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 ...
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 ...
Surface acoustic waves in rotating orthorhombic crystals
(The Royal Society, 2004-02-08)
The propagation of surface (Rayleigh) waves over a rotating orthorhombic crystal is studied. The crystal possesses three crystallographic axes, normal to the symmetry planes: the half¿space is cut along a plane normal to ...
