Evaluation of effective wave velocities in polycrystalline materials using the ultrasonic reflection matrix
Gatien Clément, Alexandre Aubry, Cécile Brütt +2
In-depth characterization of heterogeneous materials has long been a challenge in non-destructive testing. Here, a method is proposed to determine the elastic constants of metallic…
Guided elastic waves for soft elastomer characterization: an alternative to conventional rheometry
Samuel Croquette, Pierre Chantelot, Daniel A. Kiefer +2
Elastic wave propagation is intrinsically sensitive to the mechanical properties of the medium through which it travels. In soft elastomers, this makes guided elastic waves natural…
Wave propagation in a model artery
Pierre Chantelot, Alexandre Delory, Claire Prada +1
Fluid filled pipes are ubiquitous in both man-made constructions and living organisms. In the latter, biological pipes, such as arteries, have unique properties as their walls are…
Elastic wavepackets crossing a space-time interface
Alexandre Delory, Claire Prada, Maxime Lanoy +3
The interaction between waves and evolving media challenges traditional conservation laws. We experimentally investigate the behavior of elastic wave packets crossing a moving inte…
Extreme wave skewing and dispersion spectra of anisotropic elastic plates
Daniel A. Kiefer, Sylvain Mezil, Claire Prada
Guided wave dispersion is commonly assessed by Fourier analysis of the field along a line, resulting in frequency-wavenumber dispersion curves. In anisotropic plates, a point sourc…
Reflection Measurement of the Scattering Mean Free Path at the Onset of Multiple Scattering
Antton Goïcoechea, Cécile Brütt, Arthur Le Ber +5
Multiple scattering of waves presents challenges for imaging complex media but offers potential for their characterization. Its onset is actually governed by the scattering mean fr…
Supersonic shear wave imaging in stretched soft strips: modeling for quantitative elastography
Alexandre Delory, Daniel A. Kiefer, Claire Prada +1
Objective - Shear wave elastography has enriched ultrasound medical imaging with quantitative measurements of tissue stiffness. However, this method still suffers from some limitat…
Viscoelastic dynamics of a soft strip subject to a large deformation
Alexandre Delory, Daniel A. Kiefer, Maxime Lanoy +3
To produce sounds, we adjust the tension of our vocal folds to shape their properties and control the pitch. This efficient mechanism offers inspiration for designing reconfigurabl…
Beating resonance patterns and extreme power flux skewing in anisotropic elastic plates
Daniel A. Kiefer, Sylvain Mezil, Claire Prada
Elastic waves in anisotropic media can exhibit a power flux that is not collinear with the wave vector. This has notable consequences for waves guided in a plate. Through laser-ult…
