Elastic constants of polycrystalline steel evaluated with laser generated surface acoustic waves
Damien Gasteau, Nikolay Chigarev, Lili Ducousso-Ganjehi +4
We report on a laser generated and detected surface acoustic wave method for evaluating the elastic constants of micro-crystals composing polycrystalline steel. The method is based…
Asymmetric acoustic propagation of wave packets via the self-demodulation effect
Thibaut Devaux, Vincent Tournat, Olivier Richoux +1
This article presents the experimental characterization of nonreciprocal elastic wave transmission in a single-mode elastic waveguide. This asymmetric system is obtained by couplin…
Surface waves in granular phononic crystals
Helene Pichard, Aroune Duclos, Jean-Philippe Groby +3
The existence of surface elastic waves at a mechanically free surface of granular phononic crystals is studied. The granular phononic crystals are made of spherical particles distr…
Nonlinear Hysteretic Torsional Waves
J. Cabaret, P. Béquin, G. Theocharis +3
We theoretically study and experimentally report the propagation of nonlinear hysteretic torsional pulses in a vertical granular chain made of cm-scale, self-hanged magnetic beads.…
