Surface impedance and topologically protected interface modes in one-dimensional phononic crystals
Antonin Coutant, Bruno Lombard
When semi-infinite phononic crystals (PCs) are in contact, localized modes may exist at their boundary. The central question is generally to predict their existence and to determin…
Crossover Between Quantum and Classical Waves and High Frequency Localization Landscapes
David Colas, Cédric Bellis, Bruno Lombard +1
Anderson localization is a universal interference phenomenon occurring when a wave evolves through a random medium and it has been observed in a great variety of physical systems,…
Time-domain investigation of a cylindrical acoustic external cloak
Sebastien Guenneau, Bruno Lombard, Cedric Bellis
Space folding techniques based on non-monotonic transforms lead to a new class of cylindrical isotropic acoustic cloaks with a constant negative density and a spatially varying neg…
Plane-strain waves in nonlinear elastic solids with softening
Harold Berjamin, Bruno Lombard, Guillaume Chiavassa +1
Propagation of elastic waves in damaged media (concrete, rocks) is studied theoretically and numerically. Such materials exhibit a nonlinear behavior, with long-time softening and…
Nonlinear waves in solids with slow dynamics: an internal-variable model
H Berjamin, N Favrie, B Lombard +1
In heterogeneous solids such as rocks and concrete, the speed of sound diminishes with the strain amplitude of a dynamic loading (softening). This decrease known as "slow dynamics"…
A two-way model for nonlinear acoustic waves in a non-uniform lattice of Helmholtz resonators
Jean-François Mercier, Bruno Lombard
Propagation of high amplitude acoustic pulses is studied in a 1D waveguide connected to a lattice of Helmholtz resonators. An homogenized model has been proposed by Sugimoto (J. Fl…
