In-plane backward and Zero-Group-Velocity guided modes in rigid and soft strips
Jérôme Laurent, Daniel Royer, Claire Prada
Elastic waves guided along bars of rectangular cross section exhibit complex dispersion. This paper studies in-plane modes propagating at low frequencies in thin isotropic rectangu…
Laser beam shaping for enhanced Zero-Group Velocity Lamb modes generation
François Bruno, Jérôme Laurent, Paul Jehanno +2
Optimization of Lamb modes induced by laser can be achieved by adjusting the spatial source distribution to the mode wavelength (). The excitability of Zero-Group Velocity (ZGV)…
Investigation of interfacial stiffnesses of a tri-layer using Zero-Group Velocity Lamb modes
Sylvain Mezil, François Bruno, Samuel Raetz +3
Zero-Group Velocity (ZGV) Lamb waves are studied in a structure composed of two plates bonded by an adhesive layer. The dispersion curves are calculated for a Duralumin/epoxy/Dural…
Laser induced Zero-Group Velocity resonances in Transversely Isotropic cylinder
Jérôme Laurent, Daniel Royer, Takasar Hussain +2
The transient response of an elastic cylinder to a laser impact is studied. When the laser source is a line perpendicular to the cylinder axis, modes guided along the cylinder are…
Non contact probing of interfacial stiffnesses between two plates by Zero-Group Velocity Lamb modes
Sylvain Mezil, Jérôme Laurent, Daniel Royer +1
A non contact technique using Zero-Group Velocity (ZGV) Lamb modes is developed to probe the bonding between two solid plates coupled by a thin layer. The layer thickness is assume…
Temporal behavior of laser induced elastic plate resonances
Jérôme Laurent, Daniel Royer, Claire Prada
This paper investigates the dependence on Poisson's ratio of local plate resonances in low attenuating materials. In our experiments, these resonances are generated by a pulse lase…
Holographic imaging of surface acoustic waves
Francois Bruno, Jérôme Laurent, Daniel Royer +1
We report on an experimental demonstration of surface acoustic waves monitoring on a thin metal plate with heterodyne optical holography. Narrowband imaging of local optical pathle…
