Rayleigh wave characteristic motion
WebThe effects of multiple modes on Rayleigh wave dispersion are discussed to reduce the ambiguity of uniqueness of shear wave velocity (V s) profiles estimated by the surface … 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 … 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 • Phonon • S-wave See more Rayleigh waves are a type of surface wave that travel near the surface of solids.
