Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

Phononic crystals (PnCs) and acoustic metamaterials (AMMs) are artificially architected
materials endowed with the capabilities of wave manipulation. This review specifically …

We propose a new nonlinear elastic metamaterial which shows tunable bandgap at quasi-
static frequency, starting from zero frequency. While there have been active researches on …

In this paper we review recent progress on the analysis, experimental exploration, and
application of elastic wave propagation in weakly nonlinear media and metamaterials. We …

Metamaterials are artificial microstructured media that exhibit unique effective material
properties and can be tailored to achieve negative properties that inhibit the propagation of …

This paper reports the dynamic effects leveraged into one-dimensional metastructures by
Duffing-and Nonlinear Energy Sink (NES)-type piezoelectric attachments. The versatility of …

Current research on mechanical metastructures cannot achieve extremely wide and low
bandgaps because of engineering constraints, such as size, stability, and weight. To isolate …

Including nonlinearity can lead to fascinating wave propagation behavior in phononic
crystals, broadening their possible applications in acoustic engineering. The current work …

Recently, the concept of effective phononic crystals (EPCs) and locally resonant effective
phononic crystals (LREPCs) have been proposed to enable properties of phononic crystals …

The rotation of mechanical systems can greatly change their modal and wave propagation
response. In the classic example of the Foucault pendulum, the Coriolis force from the …
