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…

Impact load mitigation in sandwich beams using local resonators
B. Sharma, C. T. Sun
Dynamic response of sandwich beams with resonators embedded in the cores subjected to impact loads is studied. Using finite element models the effectiveness of various local resona…

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…
