Relating wave frequency and pore fluid homogeneity in quasi-saturated sands [PDF]
E3S Web of Conferences, 2023 P-wave velocity is regularly proposed as a proxy for water saturation when studying quasisaturated soils. However, several authors have underlined that this velocity can only be reliably correlated to water saturation if the pore fluid is “homogeneous ...

Effect of Wave Attenuation on Shear Wave Velocity Determination Using Bender Element Tests
Sensors, 2022 Wave attenuation is a widespread physical phenomenon in most acoustic tests, but there is a scarcity of quantitative investigations into the influence of wave attenuation on the determination of shear wave travel time in bender element tests.

Wavelet analysis of bender element signals [PDF]
Géotechnique, 2012 Accurate determination of shear wave arrival time using bender elements may be severely affected by a combination of near-field effects and reflected waves. These may mask the first arrival of the shear wave, making its detection difficult in the time domain. This paper describes an approach for measuring the shear wave arrival time through analysis of
