Optical generation and detection of elastic waves in solids
In this paper we review optical methods suitable to generate and to detect elastic waves in solids without any mechanical contact. The mechanisms underlying elastic wave generation by the impact of a pulsed laser beam are outlined. The principles of optical techniques able to detect surface displacements of amplitude less than one angstrom are described. Examples of applications in domains such...
متن کاملOn Rayleigh waves in incompressible orthotropic elastic solids.
In this paper the secular equation for the Rayleigh wave speed in an incompressible orthotropic elastic solid is obtained in a form that does not admit spurious solutions. It is then shown that inequalities on the material constants that ensure positive definiteness of the strain-energy function guarantee existence and uniqueness of the Rayleigh wave speed. Finally, an explicit formula for the ...
متن کاملFinite amplitude elastic waves propagating in compressible solids.
The paper studies the interaction of a longitudinal wave with transverse waves in general isotropic and unconstrained hyperelastic materials, including the possibility of dissipation. The dissipative term chosen is similar to the classical stress tensor describing a Stokesian fluid and is commonly used in nonlinear acoustics. The aim of this research is to derive the corresponding general equat...

15 صفحه اولInstabilities in elastic accelerated solids
When a solid plate is accelerated by an external pressure 0 p an instability similar to the Rayleigh-Taylor one appears if the plate is not perfectly flat. Due to the elastoplastic properties of the material the growth of the instability is lower than in a pure fluid case. In a very simple interpretation, the pressure difference across the irregular surface provokes the instability that can be ...
