Time and frequency domain evaluation of bender element systems
Géotechnique, 2015Bender elements are used to measure the low-strain shear-wave velocity of soils in many geotechnical laboratories worldwide. Despite their popularity, the method remains without a standard, mainly owing to the difficulties in controlling the actual behaviour of the bender element inside the specimen.

Characteristics of meta-kaolin geopolymer Bender-Element (BE) test
Materials Today: Proceedings, 2018Abstract Bender element (BE) test is a non-destructive test and is commonly used as an ultrasonic shear wave (S-wave) technique for determining the stiffness of materials. In this research, the ultrasonic shear wave was measured by using the piezoceramic BE in order to monitor the setting and the hardening process of meta-kaolin based geopolymer (MKG)

A simple approach for assessing the quality of bender elements
Géotechnique LettersBender elements are frequently used in geotechnical laboratories worldwide. In the first decades of introducing bender elements for soil testing, in the 1980s and 1990s, the quality of the bender elements was a main research topic. After noticeable findings about wiring, shielding, and other design features, the focus of the research moved towards ...

Determination of the Material Damping Ratio with the Bender Element Test
Journal of Geotechnical and Geoenvironmental Engineering, 2008The bender element test has shown to be a reliable tool to determine the shear wave velocity. This paper aims to extend the bender element technique to also measure the material damping ratio in a triaxial cell. Three different interpretation techniques are developed for this purpose. The first technique uses a modal test of a cylindrical soil specimen

Novel methods of bender element test analysis
2015The 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.

A comprehensive view of measuring soil stiffness with bender elements
2009A laboratory experiment to determine the shear wave velocity of geomaterials by using bender elements has been reviewed. Problems associated with uniqueness and objectivity in judging correct arrival time and uniformity in interpretations are analyzed by using experimental results from a consolidation test on reconstituted clay samples.

The assessment of destructuration of bothkennar clay using bender elements
2006Natural soft clays are structured' as a result of their history of deposition, cementing and aging. The natural clay possesses a higher void ratio and greater undrained strength than its reconstituted counterpart due to its structure, and thus exists outside the state boundary surface for the reconstituted material.
