Local resonance and Bragg bandgaps in sandwich beams containing periodically inserted resonators
Bhisham Sharma, Chin-Teh Sun
We study the low frequency wave propagation behavior of sandwich beams containing periodically embedded internal resonators. A closed form expression for the propagation constant i…
Acoustic metamaterial with negative modulus and a double negative structure
Bhisham Sharma, Chin-teh Sun
An acoustic negative bulk modulus metamaterial based on the concept of expansion chambers is proposed. It is shown that addition of a neck region to an ordinary expansion chamber i…
Analytical coupled vibroacoustic modeling of membrane-type acoustic metamaterials: plate model
Yangyang Chen, Xiaoming Zhou, Gengkai Hu +2
By considering the membrane's dissipation, the membrane-type acoustic metamaterial (MAM) has been demonstrated as a super absorber for low-frequency sound. In the paper, a theoreti…
Analytical coupled vibroacoustic modeling of membrane-type acoustic metamaterials: membrane model
Yangyang Chen, Xiaoming Zhou, Gengkai Hu +2
Membrane-type Acoustic Metamaterials (MAMs) have demonstrated unusual capacity in controlling low-frequency sound transmission/reflection. In this paper, an analytical vibroacousti…
