Numerical modelling of bender element test in soils
Measurement: Journal of the International Measurement Confederation, 2020Abstract Shear and compression wave velocities (Vs and Vp, respectively) are considered to be very useful for determining various dynamic properties of soils such as small strain shear modulus, Gmax, elastic modulus, Emax and the Poisson’s ratio, ν. Moreover, the index as well as engineering properties of the soil mass can be directly or indirectly ...

Measuring Shear Wave Velocity Using Bender Elements
Geotechnical Testing Journal, 2005 Abstract The use of bender element to measure shear wave velocity is popular due to its simplicity. However, there are still some uncertainties in the interpretation of the bender element test. In this paper, the use of bender elements in the determination of shear wave velocities of dry, unsaturated, and saturated soil specimens is ...

Determination of the Material Damping Ratio with the Bender Element Test
Journal of Geotechnical and Geoenvironmental Engineering, 2008 The 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

Determination of damping ratios for soils using bender element tests
Soil Dynamics and Earthquake Engineering, 2018 The use of bender elements to measure small-strain soil properties in the laboratory has become increasingly accessible in recent years. Coupled with the fact that bender elements can be incorporated into conventional test apparatuses such as the ...

Modeling a bender element test using Abaqus Finite Element Program [PDF]
, 2011 Finite Element Methods hold promise for modeling the behavior of an unsaturated soil specimen subjected to bender element agitation. The immediate objective of this research project is to reproduce a bender element test using Abaqus Finite Element Software assuming elastic and isotropic conditions.

Measurement Biases in the Bender Element Test
Journal of Geotechnical and Geoenvironmental Engineering, 2007This paper reconsiders the signals that are transmitted in bender element tests and the associated transfer functions to identify the problems that bias the velocity (travel time) determination. The findings of the numerical and physical experiments show that errors appearing in the velocity estimation can be traced to (1) the near-field effect and (2)

Analysis of Bender Element Tests
Geotechnical Testing Journal, 1998Abstract A study is presented of potential errors in, and methods of interpreting, the results of cantilever-type, piezoceramic bender element tests for measuring the shear wave velocity of laboratory soil specimens. Interpretations based on the first direct arrival in the output signal are often masked by near-field effects and may be ...

A Toolbox for the Automatic Interpretation of Bender Element Tests in Geomechanics
2022The 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.

Instrumentation for bender element testing of soils
International Journal of Geotechnical Engineering, 2008AbstractDetermination of shear wave velocity in sands is necessary for safety of various civil engineering structures. With this in view, earlier researchers have employed, mainly, resonant column and bender elements to determine this parameter. However, resonant column tests can only be performed in especially designed apparatus, which is not only ...
