Wave propagation through a structured medium has attracted the attention of researchers for
centuries due to its relevance to problems in condensed matter physics, chemistry, optics …

Mechanical metamaterials are man-made composite structures or materials constructed
from artificial microstructural units with extraordinary static/dynamic properties not found in …

A novel metamaterial beam with embedded quasi-zero-stiffness (QZS) resonator is
proposed to realize wave attenuation in very low-frequency band gaps. The configuration of …

Elastic/acoustic metamaterials made from locally resonant arrays can exhibit bandgaps at
wavelengths much longer than the lattice size for various applications spanning from low …

Locally resonant metamaterials are characterized by bandgaps at wavelengths that are
much larger than the lattice size, enabling low-frequency vibration attenuation. Typically …

We investigate theoretically the band structure of flexural waves propagating in an elastic
metamaterial thin plate. Kirchhoff-Love thin plate theory is considered. We study the …

Various strategies have been proposed in recent years in the field of mechanical
metamaterials to widen band gaps emerging due to either Bragg scattering or to local …

Achieving vibration and/or wave attenuation with locally resonant metamaterials has
attracted a great deal of attention due to their frequency dependent negative effective mass …

In this study, a novel plate-type resonator is proposed, and the bandgap properties of a
metamaterial sandwich plate containing a two-dimensional periodic array of these plate-type …

In this paper, a novel fluid-conveying phononic crystal (PC) pipe model is proposed. The
pipe is composed of different materials arranged alternately, and an axially spinning motion …
