Rayleigh wave propagation
WebMar 1, 2003 · Under a plane-strain state in a half-plane covered with a homogeneous prestressed layer, the Rayleigh-wave propagation along the layer is investigated. The investigations are carried out within the framework of a piecewise homogeneous body model with the use of the three-dimensional linearized theory of elasticity. Complete and … Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, and are frequently used in non-destructive testing for detecting defects.
