The pipes conveying fluid are concerned as extremely significant fluid-solid coupling
structures due to the extensive application in the many engineering fields, but poor …

Mechatronic metamaterials are of utmost significance in vibration isolation owing to their
tunable bandgaps. However, their intricate mechanisms are always challenging for …

With the development of nonlinear vibration isolation theory, a vibration isolation method of
quasi-zero stiffness (QZS) has received more and more attention. It can achieve high-static …

Topological insulators hold promises to realize exotic quantum phenomena in electronic,
photonic, and phononic systems. Conventionally, topological indices, such as winding …

The roton-like dispersions support the “return flow” of acoustic waves; such phenomena
were only observed in quantum systems. In this paper, we aim to investigate the nonlinear …

In many cases, the hybridization of two or more excitation modes in solids has led to new
and useful dispersion relations of waves. Well‐studied examples are phonon polaritons …

In our previous work, we have shown that nonlocal interactions in acoustic metamaterials
can lead to highly unusual roton-like dispersion relations exhibiting a minimum of frequency …

A theoretical paper based on chiral micropolar effective‐medium theory suggested the
possibility of unusual roton‐like acoustical‐phonon dispersion relations in 3D elastic …

We report a new method to tailor the entire two-dimensional (2D) dispersion relation based
on nonlocal phononic crystals, where beyond-nearest-neighbor (BNN) interactions are used …

This paper presents a refined model for a mechanical diode based on a mass-spring
system. The proposed model utilizes a bilinear spring to construct a frequency converter …
