Modeling a bender element test using Abaqus Finite Element Program
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. …

Development of instrumented oedometer incorporated with bender element and electrical conductivity
… oedometer was developed by incorporating bender element transducers and electrical conductivity probe to investigate and correlate the compressibility, shear wave velocity (Vs) and electrical conductivity (EC) characteristics of solidified dredged marine clay and refined kaolin. Ordinary …

Development and application of bender element field sensor for pavement base/subbase modulus characterization and geogrid effectiveness evaluation
Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2025-12-01

The study of shear and longitudinal velocity measurements of sands and cohesive soils
… of soils, with an emphasis on the use of bender element technology in obtaining the shear modulus. The experimental program consisted two primary stages. The beginning part of the experimentation was concerned with evaluating the behavior of bender elements, both free-standing and when …

Combining seismic and geotechnical methods to improve the prediction of physical soil properties
… the geotechnical methods. The seismic data (i.e. bender element data) needs to be correlated with geotechnical data allowing it to be adopted in engineering designs. However, the procedures and analysis of bender element (BE) data can be subjected to crucial errors due to several limitations in …

The measurement and interpretation of small strain stiffness of soils
… while dynamic stiffnesses were measured using bender elements. Using the two methods good agreement was found between the stiffnesses at 0.0001% strain for two different materials. Bender elements measure the propagation time of shear waves through a soil sample so that the value of Gnax can be …

Investigation of Elastic Parameters and Pavement Modeling With Eps Geofoam
… obtained from flexure, nondestructive (ND) and bender element (BE) tests. ND and BE tests also produced higher Poisson's ratio values based on observations of P and S wave velocities. Compression tests under lateral deformation restraint, with observation of lateral deformations using proximity …

Mechanical characteristics of organically modified fly ash-kaolinite mixtures
… self-developed floating wall-type consolidometer bender element testing system. Vs results showed that PEO and chitosan increased Vs of the fly ash-kaolinite mixtures, while xanthan gum decreased V<sub>s</sub>. V<sub>s</sub> anisotropy of the fly ash-kaolinite mixtures was decreased by the …

Relationship between decomposition level and induced solidification of peat based on laboratory investigation
… the unconfined compressive strength (UCS) test, bender element (BE) test and the same chemical tests as applied for the original sample. The mix ratios examined were of four types being 100 % OPC, 50 % OPC 50 % BA, 50 % OPC 25 % BA 25 % FA and 25 % OPC 50 % BA 25 % FA. Two water-binder ratios …

Cyclic response of Gulf of Mexico clay from the Walker Ridge
… and strength properties; 2. Based on laboratory bender element tests on GOM clay and an extensive literature review on the small-strain shear modulus of soft clays, simple predictive tools are proposed that could allow the seismic geotechnical practioner to estimate Gmax for a soft clay; 3. The …

Movements around a tunnel in two-layer ground
… geotechnical centrifuge model testing and finite element analysis using the 3-Surface Kinematic Hardening (3-SKH) model, an elasto-plastic soil model implemented in the finite element program CRISP at City University, London. Both methods use effective stress path modelling to produce soil …
