#### Seismic Rayleigh waves on an exponentially graded, orthotropic half-space

(The Royal Society, 2007)

Efforts at modelling the propagation of seismic waves in half-spaces with continuously varying properties have mostly been focused on shear-horizontal waves. Here, a sagittally polarized (Rayleigh type) wave travels along ...

#### An algorithm for the unit group of the Burnside ring of a finite group

(Cambridge University Press, 2007-01)

In this note we present an algorithm for the construction of the unit group of
the Burnside ring Ω(G) of a finite group G from a list of representatives of the
conjugacy classes of subgroups of G.

#### A quiver presentation for Solomon's descent algebra

(Elsvier, 2009)

The descent algebra S(W) is a subalgebra of the group algebra of a finite Coxeter group W, which supports a homomorphism with nilpotent kernel and commutative image in the character ring of W. Thus S(W) is a basic algebra, ...

#### Finite amplitude inhomogeneous waves in Mooney-Rivlin viscoelastic solids

(Elsevier, 2004-09)

New exact solutions are exhibited within the framework of finite viscoelasticity. More precisely, the solutions correspond to finite-amplitude, transverse, linearly polarized, inhomogeneous motions superposed upon a finite ...

#### Rayleigh waves and surface stability for Bell materials in compression; comparison with rubber

(Oxford University Press, 2003)

The stability of a Bell-constrained half-space in compression is studied. To this end, the propagation of Rayleigh waves on the surface of the material when it is maintained in a static state of triaxial prestrain is ...

#### Bleustein-Gulyaev waves in some functionally graded materials

(Elsevier, 2006-02-28)

Functionally Graded Materials are inhomogeneous elastic bodies whose properties vary continuously with space. Hence consider a half-space (x2>0) occupied by a special Functionally Graded Material made of an hexagonal (6 ...

#### Non-principal surface waves in deformed incompressible materials

(Elsevier, 2005)

The Stroh formalism is applied to the analysis of infinitesimal surface wave propagation in a statically, finitely and homogeneously deformed isotropic half-space. The free surface is assumed to coincide with one of the ...

#### Surface waves in a deformed isotropic hyperelastic material subject to an isotropic internal constraint

(Elsevier, 2004)

An isotropic elastic half-space is prestrained so that two of the principal axes of strain lie in the bounding plane, which itself remains free of traction. The material is subject to an isotropic constraint of arbitrary ...

#### Inhomogeneous "longitudinal" plane waves in a deformed elastic material

(Springer, 2005-01)

By definition, a homogeneous isotropic compressible Hadamard material has the property that an infinitesimal longitudinal homogeneous plane wave may propagate in every direction when the material is maintained in a state ...

#### Explicit secular equations for piezoacoustic surface waves: Shear-horizontal modes

(AIP Publishing, 2005-09-06)

The existence of a two-partial Rayleigh wave coupled to an electrical field in 2 mm piezoelectric crystals is known but has rarely been investigated analytically. It turns out that the Z cut X propagation problem can be ...
