Refraction of Surface Gravity Waves by Shear Waves [PDF]
Journal of Physical Oceanography, 2006 Abstract Previous field observations indicate that the directional spread of swell-frequency (nominally 0.1 Hz) surface gravity waves increases during shoreward propagation across the surf zone. This directional broadening contrasts with the narrowing observed seaward of the surf zone and predicted by Snell’s law for bathymetric ...

APL Bioengineering, 2023 Recently, supershear Rayleigh waves (SRWs) have been proposed to characterize the biomechanical properties of soft tissues. The SRWs propagate along the surface of the medium, unlike surface Rayleigh waves, SRWs propagate faster than bulk shear waves ...

The Velocity of Shear Waves in Saturated Soil [PDF]
Soil Science Society of America Journal, 2011 The velocities of shear waves in three different soils were measured as a function of consolidation using a Bishop and Wesley triaxial cell. We considered the soil deforming plastically on the normal consolidation line as well as elastic deformation on the rebound curve.

Kinematics of the Ship’s Wake in the Presence of a Shear Flow
Journal of Marine Science and Engineering, 2020 We present the kinematic model of the ship wake in the presence of horizontal subsurface current linearly varying with the depth of water. An extension of the Whitham–Lighthill theory for calm water is developed.

A new method for shear wave speed estimation in shear wave elastography
IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control, 2015 Visualization of mechanical properties of tissue can aid in noninvasive pathology diagnosis. Shear wave elastography (SWE) measures the elastic properties of soft tissues by estimation of local shear wave propagation speed. In this paper, a new robust method for estimation of shear wave speed is introduced which has the potential for simplifying ...

S-wave propagating in an anisotropic inhomogeneous elastic medium under the influence of gravity, initial stress, electric and magnetic field [PDF]
Theoretical and Applied Mechanics, 2014 The purpose of this paper is to study the effect of gravity, initial stress, non-homogeneity, electric and magnetic field on the propagation of shear waves in an anisotropic incompressible medium. Various graphs are plotted to show the effect of
