An Analytic Study on the Dispersion of Love Wave Propagation in Double Layers Lying Over Inhomogeneous Half-Space
In this work, attempts are made to study the dispersion of Love waves in dry sandy layer sandwiched between fiber reinforced layer and inhomogeneous half space.Inhomogeneity in half space associated with density and rigidity and considered in exponential form. Displacement components for fiber reinforced layer, dry sandy layer and inhomogeneous half-space have been obtained by using method of s...
متن کاملDispersion of Love Waves in a Composite Layer Resting on Monoclinic Half-Space
Dispersion of Love waves is studied in a fibre-reinforced layer resting on monoclinic half-space. The wave velocity equation has been obtained for a fiber-reinforced layer resting on monoclinic half space. Shear wave velocity ratio curve for Love waves has been shown graphically for fibre reinforced material layer resting on various monoclinic half-spaces. In a similar way, shear wave velocity ...
متن کاملWave transport for a scalar model of the Love waves
We study transport for a scalar model of Love waves. These waves arise in the propagation of seismic waves whose energy is concentrated in the vicinity of the earth surface. We derive radiative transfer equations from rst principles for the angularly resolved energy density of the Love waves in a simpliied acoustic model. We consider a rough top surface with weak uctuations at the scale of the ...
متن کاملDispersion of Discontinuous Periodic Waves
The dynamic evolution of linearly dispersive waves on periodic domains with discontinuous initial profiles is shown to depend dramatically upon the asymptotics of the dispersion relation at large wave number. Asymptotically linear or sublinear dispersion relations produce slowly changing waves, while those with polynomial growth exhibit dispersive quantization, a.k.a. the Talbot effect, being (...
متن کاملMeasurement of phase velocity dispersion curves and group velocities in a plate using leaky Lamb waves
The guided wave has been widely employed to characterize thin plates and layered media. The dispersion curves of phase and group velocities are essential for the quantitative application of guided waves. The technique using leaky Lamb wave (LLW) is one of the excellent methods to obtain dispersion curves. In the present work, a fully automated system for the measurement of LLW has been develope...
