A new method to identify elastic wave propagation mode and polarized bandgaps in periodic solid media
Maria Jose Carrillo Munoz, Bhisham Sharma
We present a new computational method for the accurate identification of the propagation modes and polarizations of elastic waves propagating in periodic solid structures and metam…
Sound Absorption and Transmission Loss Properties of Open-Celled Aluminum Foams with Stepwise Relative Density Gradients
Amulya Lomte, Bhisham Sharma, Mary Drouin +1
We investigate the acoustical properties of uncompressed and compressed open-celled aluminum metal foams fabricated using a directional solidification foaming process. We compresse…
Additive Manufacturing of Fibrous Sound Absorbers
William Johnston, Bhisham Sharma
We investigate the possibility of additively manufacturing fibrous sound absorbers using fused deposition modeling. Two methods for 3D printing fibers are proposed. The fiber bridg…
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…
