Shear wave filtering in naturally-occurring Bouligand structures.
(ELSEVIER SCI LTDUniversidad EAFIT. Departamento de Ingeniería Mecánica, 2015-09-01)
Wave propagation was investigated in the Bouligand-like structure from within the dactyl club of the stomatopod, a crustacean that is known to smash their heavily shelled preys with high accelerations. We incorporate the ...
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 ...
Comparison of acoustoelastic methods to evaluate stresses in steel plates and bars

Simulação numérica de Roll Waves em escoamentos turbulentos
(Universidade Estadual Paulista (Unesp), 2020-01-28)
Roll waves são instabilidades que, em condições favoráveis, podem surgir em escoamentos com superfície livre e que se propagam como um trem de ondas com velocidade e comprimento bem definidos. Tais instabilidades podem ...
PROPAGACIÓN DE ONDAS EN UN MEDIO FLUIDO INMERSO EN UN SÓLIDO ELÁSTICO AGRIETADO, UTILIZANDO EL MÉTODO DE DIFERENCIAS FINITAS
(2010-10-26)
The presence of irregularities (cracks) in elastic materials leads to dispersion and
diffraction during propagation of waves. This diffracted field produced during the
propagation of waves provides valuable information ...
