Unfolding engineering metamaterials design: relaxed micromorphic modeling of large-scale acoustic meta-structures
F. Demore, G. Rizzi, M. Collet +2
In this paper, we present a unit cell showing a band-gap in the lower acoustic domain. The corresponding metamaterial is made up of a periodic arrangement of this unit cell. We rig…
Innovative Electroacoustic resonator Control enforcing Duffing dynamics at moderate excitation levels: conception and experimental validation
Emanuele De Bono, Maxime Morell, Manuel Collet +3
The electroacoustic resonator is an effcient electro-active device for noise attenuation in enclosed cavities or acoustic waveguides. It is made of a loudspeaker (the actuator) and…
Design and characterization of an instrumented slider aimed atmeasuring local micro-impact forces between dry rough solids
Camille Grégoire, Bernard Laulagnet, Joël Perret Liaudet +3
Sliding motion between two rough solids under light normal loading involves myriad micro-impacts between antagonist micro-asperities. Those micro-impacts are at the origin of many…
Exploring metamaterials' structures through the relaxed micromorphic model: switching an acoustic screen into an acoustic absorber
Gianluca Rizzi, Manuel Collet, Félix Demore +3
While the design of always new metamaterials with exotic static and dynamic properties is attracting deep attention in the last decades, little effort is made to explore their inte…
Experimental Realization of a Reconfigurable Electroacoustic Topological Insulator
Amir Darabi, Manuel Collet, Michael J Leamy
A substantial challenge in guiding elastic waves is the presence of reflection and scattering at sharp edges, defects, and disorders. Recently, mechanical topological insulators ha…
Numerical optimization of a prestressed auxetic metamaterial for vibration isolation
Adrien Pyskir, Manuel Collet, Zoran Dimitrijevic +1
We present a numerical study on an enhanced periodic auxetic metamaterial. Rotating squares mechanism allied to precompression induced buckling give these elastic structures exotic…
