Rayleigh waves motion
WebThe propagation and properties of Rayleigh waves on curved surfaces are investigated theoretically. The Rayleigh wave dispersion equation for propagation on a curved surface is derived as a parabolic equation, and its penetration depth is analyzed using the curved surface boundary. Reciprocity is introduced to model the diffracted Rayleigh wave ... WebNov 7, 2024 · Rayleigh-wave motion is in fact frequency dependant (low frequencies are influenced by the characteristics of the deep layers, while the high frequencies depend on the shallow materials). In this respect, compared to the polarity analysis presented in Gribler et al. , the RPM frequency curve benefits in particular from two important features:

Rayleigh waves can circle the globe multiple times after a large earthquake and still be measurably large. There is a difference in the behavior (Rayleigh wave velocity, displacements, trajectories of the particle motion, stresses) of Rayleigh surface waves with positive and negative Poisson's ratio. See more 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, … See more Rayleigh waves are widely used for materials characterization, to discover the mechanical and structural properties of the object being tested – like the presence of cracking, and the related shear modulus. This is in common with other types of surface … See more Generation from earthquakes Because Rayleigh waves are surface waves, the amplitude of such waves generated by an earthquake generally decreases … See more • Linear elasticity • Longitudinal wave • Love wave • P-wave See more Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in … See more Rayleigh waves propagating at high ultrasonic frequencies (10–1000 MHz) are used widely in different electronic devices. In addition to Rayleigh waves, some other types of surface acoustic waves (SAW), e.g. Love waves, are also used for this purpose.
