The existence of a symmetric mode in an elastic solid wedge for all admissible values the Poisson ratio and arbitrary openings close to $\pi$ has been proven.

When a stressed solid is in contact with an environment (a vapor or a liquid solution), the solid may gain mass from, or lose mass to, the environment. The surface reaction is driven by the interfacial and elastic energy and by the chemical potential di€erence between the solid and the environment. This paper presents a ®nite element method to simulate the stress-assisted surface reaction. The ...

It is shown that whether or not diffractive scattering is observed from solid surfaces depends not only on the elastic scattering cross section, ie the normalized Debye-Waller factor, as has been recently suggested by J L Beeby but also on the surface structure or local surface potential of the particular solid.

A method is suggested for defining a deformation-dependent free energy in microscopic terms for a deformed elastic solid and applied to a simple microscopic model of such a solid. Some of the convexity and continuity properties of this free energy function are derived.

Negative refraction of elastic waves has been studied and experimentally demonstrated in three- and two-dimensional phononic crystals, but Bragg scattering is impractical for low-frequency wave control because of the need to scale the structures to manageable sizes. Here we present an elastic metamaterial with chiral microstructure made of a single-phase solid material that aims to achieve subw...
