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

Static and dynamic characterisation of Agartala peat [PDF]
Mires and Peat, 2021 Peat is a unique soil type whose properties vary widely compared to other soils due to its high water content, low shear strength and high compressibility. Thus, construction on peat deposits is challenging and needs proper attention from engineers.

Design of an Acoustic Bender Transducer for Active Sonobuoys
Sensors, 2019 Recent underwater vehicles can operate with a much lower level of noise, which increases the need for an active sonobuoy with a high detection performance. These active sonobuoys mainly use bender transducers as a projector that emits sound waves.
