WebMar 14, 2024 · Then using this 1-D shear wave velocity model as the initial model and the Rayleigh wave group velocity map of 0.5–14 s period as inputs, we invert for the 3-D … Webrecorded Rayleigh waves (specific type of surface wave) generated using either an active and/or passive acoustic source into a 1-D shear-wave velocity profile of the subsurface. If MASW data are acquired at multiple sites along a traverse, the output 1-D shear wave velocity profiles can be used to generate a 2-D velocity image of the subsurface.

Estimation of near-surface shear-wave velocity by inversion of …
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 … See more Low frequency (< 20 Hz) Rayleigh waves are inaudible, yet they can be detected by many mammals, birds, insects and spiders. Humans should be able to detect such Rayleigh waves … See more WebBayon et al. [(2005). J. Acoust. Soc. Am. 117, 3469-3477] described a method for the determination of Young's modulus by measuring the Rayleigh-wave velocity and the … WebRayleigh waves involve interaction between P and 5 waves at a free surface; thus we must further explore the nature of body-wave reflection coefficients at the free surface.
