Estimating shear wave velocity with the SCPTu and Bender element

open access: yesIOP Conference Series: Earth and Environmental Science, 2021
Abstract The shear wave velocity (vs) is an important soil and rock property that can both be used in several geotechnical problems including for evaluation of dynamic properties of soils as well as in determining the maximum value of soil stiffness at small strain.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

A PROCEDURE TO CALIBRATE AND PERFORM THE BENDER ELEMENT TEST

open access: yesDyna, 2012
El método de ensayo bender element es utilizado en laboratorio para obtener la velocidad de la onda cortante de suelos. A pesar de su aparente simplicidad, aún no existe una norma para este ensayo. Existen factores que pueden tener alguna incidencia sobre el resultado.

Dynamic and static measurements of small strain moduli of toyoura sand

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2014
A series of triaxial tests were performed on specimens made of Toyoura sand having different dry densities. Very small unloading/ reloading cycles were applied to obtain “static” Young’s modulus.

Development of vertical and horizontal disk transducers for wave velocity measurements in a large rectangular specimen [PDF]

open access: yesE3S Web of Conferences, 2019
For the accurate design of structures subjected to both static and dynamic loadings, elastic wave velocity and small strain stiffness are essential parameters. Numerous techniques have been developed to estimate wave velocities of geomaterials.
