On the effective magnetostrictive properties of anisotropic magneto-active elastomers in the small-deformation limit
Connor D. Pierce, Kathryn H. Matlack
Magneto-active elastomers (MAEs) are composite materials comprising an elastomer matrix with embedded magnetic particles, endowing the composite with coupled effective magneto-mech…
A Quantitative Study of Energy Localization Characteristics in Defect-embedded Phononic Crystals
Vinod Ramakrishnan, Kathryn H. Matlack
Phononic crystals (PnCs) are periodic engineered media that can customize the spatio-temporal characteristics of mechanical energy propagation. PnCs that additionally leverage prec…
Subwavelength topological interface modes in a multilayered vibroacoustic metamaterial
Majdi O. Gzal, Joshua R. Tempelman, Kathryn H. Matlack +1
We present a systematic and rigorous analytical approach, based on the transfer matrix methodology, to study the existence, evolution, and robustness of subwavelength topological i…
Sub-Bragg Phenomena in Multilayered Vibroacoustic Phononic Metamaterials
Majdi O. Gzal, Lawrence A. Bergman, Kathryn H. Matlack +1
Beyond classical Bragg diffraction, we report on new sub-Bragg phenomena to achieve enhanced sound wave tunability in the low-frequency range in a multilayered acoustic metamateria…
