The Velocity of Shear Waves in Saturated Soil [PDF]

open access: yesSoil 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.

Supershear Rayleigh wave imaging for quantitative assessment of biomechanical properties of brain using air-coupled optical coherence elastography

open access: yesAPL 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 ...

Reverberant Shear Wave Elastography: A Multi-Modal and Multi-Scale Approach to Measure the Viscoelasticity Properties of Soft Tissues

open access: yesFrontiers in Physics, 2021
There are a variety of approaches used to create elastography images. Techniques based on shear wave propagation have received significant attention. However, there remain some limitations and problems due to shear wave reflections, limited penetration ...

Shear induced breaking of large internal solitary waves [PDF]

open access: yes, 2009
The stability properties of 24 experimentally generated internal solitary waves (ISWs) of extremely large amplitude, all with minimum Richardson number less than 1/4, are investigated.

Kinematics of the Ship’s Wake in the Presence of a Shear Flow

open access: yesJournal 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

open access: yesIEEE 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 ...

In situ shear wave velocity from multichannel analysis of surface waves (MASW) tests at eight Norwegian research sites [PDF]

open access: yes, 2007
The Multichannel Analysis of Surface Waves (MASW) technique, used to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has recently generated considerable interest in the geophysics community.

S-wave propagating in an anisotropic inhomogeneous elastic medium under the influence of gravity, initial stress, electric and magnetic field [PDF]

open access: yesTheoretical 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
