The importance of coupling and sample geometry in bender element testing

2015
ABSTRACT This paper presents a study aiming to improve the quality and repeatability of shear wave velocity measurements by means of the bender element (BE) technique. For this purpose, studies were carried out to improve the contact between the bender elements and the specimen, namely by the use of a BE puncher and/or the use of an ...

Automatic Shear Wave Velocity Estimation in Bender Element Testing

Geotechnical Testing Journal, 2016
Abstract Dynamic properties of soils, such as shear wave velocity and damping, are some of critical parameters in the design of civil infrastructures subjected to vibrations from earthquakes and machine foundations. Bender element (BE) testing is used in the laboratory to determine shear wave velocity; however, there is no standard ...

The Measurement of Stiffness Anisotropy in Clays with Bender Element Tests in the Triaxial Apparatus

Geotechnical Testing Journal, 1998
Abstract The paper presents the results of a program of research investigating the effectiveness of bender elements when used in conjunction with the triaxial apparatus for measuring the anisotropy of small strain stiffness of fine-grained soils. Tests were carried out on both intact and reconstituted samples of London clay and on kaolin

Novel methods of bender element test analysis

2015
The complexity of bender element test interpretation iswell documented. For example the arrival of a compressionalwave at the receiver clouds the arrival of the true shearwave. The wave diffuses while travelling through the sample as the received signal is of lower magnitude than the transmitted signal.

Haar Wavelet Transform for Arrival Time Identification in Bender Element Tests

Geotechnical Testing Journal, 2019
Abstract The determination of shear wave velocity (Vs) using bender elements can be affected by the near-field effect. This phenomenon hinders the identification of the S-wave arrival time of an output signal. Multiple alternatives have been presented to counteract these effects, including the use of wavelet transforms during the last ...
