Low-frequency wide band-gap elastic/acoustic metamaterials using the K-damping conceptTools Antoniadis, I. and Chatzi, E. and Chronopoulos, Dimitrios and Paradeisiotis, A. and Sapountzakis, I. and Konstantopoulos, S. (2017) Low-frequency wide band-gap elastic/acoustic metamaterials using the K-damping concept. Arxiv . (Unpublished) Full text not available from this repository.AbstractThe terms “acoustic/elastic meta-materials” describe a class of periodic structures with unit cells exhibiting local resonance. This localized resonant structure has been shown to result in negative effective stiffness and/or mass at frequency ranges close to these local resonances. As a result, these structures present unusual wave propagation properties at wavelengths well below the regime corresponding to band-gap generation based on spatial periodicity, (i.e. “Bragg scattering”). Therefore, acoustic/elastic meta-materials can lead to applications, especially suitable in the low-frequency range.
