GomesThe beta version of GeoHyTE (current version 1.3) can be obtained upon request from web page https://sites.google.com/view/cen-dynageo/geohyte (accessed on 1 February 2024).; The small strain shear modulus is an important characteristic of geomaterials that can be measured experimentally using piezoelectric sensors (bender elements). However, most conventional signal interpretation techniques are based on the v...
A toolbox for the automatic interpretation of bender element tests in geomechanics
Moldovan, Ionuţ Dragoş; Almukashfi, Abdalla Mustafa Abdalla; Correia, A. GomesFirst Online: 20 November 2022; The small strain shear modulus is an important characteristic of geomaterials that can be measured using bender element experiments. However, most conventional interpretation techniques are based on the visual observation of the output signal and are inherently subjective. Other techniques, based on the cross-correlation of input and output signals lack physical insight, as they ...
Optimisation of receiver’s location in bender element experiments using computa...
Moldovan, Ionuţ Dragoş; Correia, A. Gomes"Available online 23 January 2021"; Bender elements are shear wave transducers, used for the computation of small strain shear moduli of geomaterials. However, the distortion of the output signal caused by residual compression waves may lead to important errors in the shear modulus estimates. We present a novel procedure for the optimisation of the location of the receiver bender element, to avoid regions where...
Bender-based G0 measurements: A coupled numerical–experimental approach
Moldovan, Ionuţ Dragoş; Correia, A. Gomes; Pereira, CláudioBender elements are shear wave transducers, widely used for the experimental identification of the small-strain shear moduli of geomaterials. They offer good coupling with the sample and controllable loading signal and frequency, but some of their design and signal interpretation features are still under investigation. The research of these features has been approached mainly on experimental grounds and, in mos...
