Piezoelectric Ring Bender for Characterization of Shear Waves in Compacted Sandy Soils

Sensors, 2021
Shear wave velocity and small-strain shear modulus are widely used as the mechanical properties of soil. The objective of this study is to develop a new shear wave monitoring system using a pair of piezoelectric ring benders (RBs) and to evaluate the ...

Preliminary findings on the experimental investigation of the small-strain behaviour of Pizzoli silty sand [PDF]

E3S Web of Conferences
The dynamic properties of soils play a crucial role in solving many geotechnical problems with special attention to earthquake engineering. In particular, the small-strain soil behavior should be accurately reproduced in geotechnical modelling to allow ...

In situ shear wave velocity from multichannel analysis of surface waves (MASW) tests at eight Norwegian research sites

, 2007
The Multichannel Analysis of Surface Waves (MASW) technique, used to determine shear wave velocity (Vs) and hence small strain stiffness (Gmax), has recently generated considerable interest in the geophysics community.

Cyclic Loading Test for the Small-Strain Shear Modulus of Saturated Soft Clay and Its Failure Mechanism

Geofluids, 2021
Small-strain shear modulus, Gmax, is a key evaluation index to study the dynamic characteristics of soil in geotechnical engineering. It is widely adopted to evaluate the stiffness of soft soil in soil dynamic engineering.

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

Advanced 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.

Prediction models and associated uncertainty for dynamic shear modulus and damping ratio of Beijing silty clay

Scientific Reports
Based on experimental data of normalized shear modulus and damping ratio from undisturbed silty clay within 120 m depth in the Beijing area, the Davidenkov backbone curve is used to characterize the normalized shear modulus curve, and the damping ratio ...
