Soft phononic crystals have the advantages over their stiff counterparts of being flexible and
reconfigurable. Normally, the band gaps of soft phononic crystals will be modified after …

We introduce a fundamental restriction on the strain energy function and stress tensor for
initially stressed elastic solids. The restriction applies to strain energy functions that are …

In this paper we employ genetic algorithms in order to theoretically design a range of
phononic media that can act to prevent or ensure antiplane elastic wave propagation over a …

The early detection of failures in structures is a subject of great interest in engineering;
several of these techniques are linked with the elastic wave propagation, using guided …

Based on the hyperelastic material models, the propagation of nonlinear travelling waves in
cylindrical rods has been studied. Here, different types of nonlinear travelling waves in a …

We develop a series expansion approach to the calculation of the scattering coefficients of in-
plane transverse elastic waves. The waves are scattered by a cylindrical obstacle as they …

Parametric array loudspeakers (PALs) are known for their capability of generating highly
directional audio sound waves. Owing to this feature, they are used as secondary sources in …

The governing equations for small-on-large analysis of an incompressible hyperelastic solid
are reduced to a coupled system of six first-order ordinary differential equations with respect …

We describe an effective active cloaking strategy for the scalar Helmholtz equation in three
dimensions where multipole active sources are located at the vertices of the Platonic solids …
