Phononic crystals are composite materials made of periodic distributions of inclusions
embedded in a matrix. Due to their periodic structure, these materials may exhibit under …

Inspired by sonic engineering, locally resonant metamaterials have attracted much attention
from researchers in civil engineering for their unique characteristics of stress wave …

The lumped-mass method is applied to study the propagation of elastic waves in two-
dimensional binary periodic systems, ie, periodic soft rubber/epoxy and vacuum/epoxy …

The plane wave expansion method is extended to study the flexural wave propagation in
locally resonant beams with multiple periodic arrays of attached spring-mass resonators …

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 …

A uniform string with periodically attached spring–mass resonators represents a simple
locally resonant continuous elastic system whose band gap mechanisms are basic to more …

We propose a new type of concrete for the attenuation of elastic waves induced by dynamic
excitation. In this metamaterial, which we call metaconcrete, the stone, sand, and gravel …

This paper proposed a type of lightweight multilayer honeycomb membrane-type acoustic
metamaterials (AMs) and the transmission loss is studied experimentally. It is demonstrated …

Though lightweight sandwich structures have been extensively applied in practical
engineering, it remains a challenge to control wave propagation and vibration in these …

Unlike conventional metamaterials with a periodic array of identical resonators, rainbow
metamaterials consist of an array of discrete resonators with a spatially varying parameter …
