We study wave dispersion in a one-dimensional nonlinear elastic metamaterial consisting of
a thin rod with periodically attached local resonators. Our model is based on an exact finite …

Elastic wave propagation in solids composed of elastic metamaterials always exists as both
transverse and longitudinal waves simultaneously. By using the Hamilton principle, Bloch …

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 …

In this paper, we report a new type of bandgap phenomenon called “amplitude-induced
bandgap”, which is induced by amplitude in nonlinear metamaterials. Generally, bandgap …

Propagation of elastic waves in acoustic metamaterials based on locally resonant
viscoelastic phononic crystals is discussed. A variational formulation of the complex band …

We demonstrate the experimental realization of a multiresonant metamaterial for Lamb
waves, ie, elastic waves propagating in plates. The metamaterial effect comes from the …

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

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 …

There has been a rising interest in utilizing metamaterials to manipulate the propagation of
surface waves, including Rayleigh waves. These novel materials have a diverse range of …

Recent focus has been given to spectro-spatial analysis of nonlinear metamaterials since
they can predict interesting nonlinear phenomena not accessible by spectral analysis (ie …
