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 ...
Ultrasonic inspection of AA6013 laser welded joints
(ABM, ABC, ABPol, 2011-09-01)
Interest in laser beam welding for aerospace applications is continuously growing, mainly for aluminum alloys. The joints quality is usually assessed by non-destructive inspection (NDI). In this work, bead on plate laser ...
Experimental study of the complex reflection coefficient of shear waves from the solid-liquid interface
(2010-01-01)
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 ...
