Deep shear wave velocity profiles of the Santiago Basin for evaluation of seismic response
(ICSMGE, 2017)
Evaluation of the seismic response of the Santiago Basin requires a shear wave velocity model with vertical and lateral
variations that may explain the site effects reported during the 2010 Maule Earthquake. In order to ...
The mechanical performance of concrete shear key for prefabricated structures
(Sage, 2020)
The mechanical performance of concrete connection plays an important role in the response of precast concrete structures. Unlike conventional small concrete shear key which is mainly to help with alignment at installation, ...
Site characterization at Chilean strong-motion stations: Comparison of downhole and microtremor shear-wave velocity methods
(Elsevier, 2015)
A blind comparison of independent invasive (downhole, standard penetration, bender element) and noninvasive microtremor shear-wave velocity (Vs) profiling is presented for 11 strong-motion stations in central and southern ...
Faraday-wave contact-line shear gradient induces streaming and tracer self-organization: from vortical to hedgehoglike patterns
(American Physical Society, 2020)
In this Letter, we experimentally demonstrate self-organization of small tracers under the action of longitudinal Faraday waves in a narrow container. We observe a steady current formation dividing the interface in small ...
Degeneration of internal Kelvin waves in a continuous twolayer stratification
(Cambridge Univ Press, 2015)
We explore the evolution of the gravest internal Kelvin wave in a two-layer rotating cylindrical
basin, using direct numerical simulations (DNS) with a hyperviscosity/diffusion approach to
illustrate different dynamic ...
Experimental study of the complex reflection coefficient of shear waves from the solid–liquid interface
(Elsevier, 2009)
The determination of the reflection coefficient of shear waves reflected from a solid-liquid interface is an important method in order to study the viscoelastic properties of liquids at high frequency. The reflection ...
Hysteretic Faraday waves
(American Physical Society, 2016)
We report on the numerical and theoretical study of the subcritical bifurcation of parametrically amplified waves appearing at the interface between two immiscible incompressible fluids when the layer of the lower fluid ...
Ultrasonic measurement of viscosity: Signal processing methodologies
(Universidad Autónoma de Occidente, 2019-01)
This work deals with two alternative methodologies for data post-processing resulting from the ultrasonic shear-wave reflectance method used for liquid viscosity measurement. In the shear-wave reflectance method, the ...
Shear-wave corner retroreflector device for ultrasonic measurement of viscosity
(Revista Ultrasonics, 2021)
This work shows a novel ultrasonic viscosity measurement device with increased sensitivity. The measuring
principle is based on the determination of the complex reflection coefficient of shear-waves at the solid–liquid
...
Combining active and passive multi-channel analysis of surface waves to improve reliability of V-S,V- 30 estimation using standard equipment
(Springer, 2015)
Surface wave methods are commonly used for seismic soil classification, however, their indirect nature implies a degree of uncertainty that needs to be described and constrained. To evaluate dispersive characteristics, we ...
