Analytical and experimental results: creation of a duffing acoustic nonlinear oscillator at low amplitudes
Maxime Morell, Manuel Collet, Emmanuel Gourdon +2
Nonlinear dynamics have long been exploited in order to damp vibrations in solid mechanics. The phenomenon of irreversible energy transfer from a linear primary system to a nonline…

The Advection Boundary Law in absence of mean flow: passivity, nonreciprocity and enhanced noise transmission attenuation
Emanuele De Bono, Manuel Collet, Morvan Ouisse
Sound attenuation along a waveguide is intensively studied for applications ranging from heating and air-conditioning ventilation systems, to aircraft turbofan engines. In particul…
