Antiplane surface acoustic waves propagating in elastic half-space coated with an anisotropic laminate
Dispersion relation of antiplane surface acoustic waves (SAWs) propagating in elastic half-space coated with an anisotropic laminate was determined explicitly by means of Stroh’s formalism within the subsonic range, where there is no energy leakage into the substrate. During the procedure, the governing dynamic equation in each anisotropic layer and the displacement–traction continuity at inter...
متن کاملInterfacial waves with surface elasticity
In this paper we study the existence and uniqueness of interfacial waves in account of surface elasticity at the interface. A sufficient condition for the existence and uniqueness of a subsonic interfacial wave between two elastic half-spaces is obtained for general anisotropic materials. Further, we explicitly calculate the dispersion relations of interfacial waves for interfaces between two s...
متن کاملThe incompressible limit in linear anisotropic elasticity, with applications to surface waves and elastostatics
Incompressibility is established for threeand two-dimensional deformations of an anisotropic linearly elastic material, as conditions to be satis ed by the elastic compliances. These conditions make it straightforward to derive results for incompressible materials from those established for compressible materials. As an illustration, the explicit secular equation is obtained for surface waves i...
متن کاملSurface instability in finite anisotropic elasticity under initial stress
The writer’s theory of surface instability of au elastic body under initial stress in finite strain is extended to anisotropic elasticity. The general characteristic equation for surface instability is derived. In addition, the surface deflexion under a normal load is evaluated for the subcritical case of initial stress. The analysis includes the case in which gravity is taken into account. It ...
متن کاملSurface Waves Propagating on Grounded Anisotropic Dielectric Slab
This paper investigates the characteristics of surface waves propagating on a grounded anisotropic dielectric slab. Distinct from the existing analyses that generally assume that the fields of surface wave uniformly distribute along the transverse direction of the infinitely large grounded slab, our method takes into account the field variations along the transverse direction of a finite-width ...
