Abstract Quasi-zero-stiffness (QZS) is beneficial to achieving wider vibration isolation band.
However, existing QZS isolators are usually configured with negative stiffness and linear …

Magnetically modulated sliding structure (MMSS) is proposed and systematically
investigated in this paper. The MMSS consists of the sliding beam and a pair of repulsive …

A meta-plate structure featuring periodic tunable-stiffness nonlinear oscillators (NLOs) are
proposed for nonlinear vibration and flutter suppressions. The tunable nonlinear stiffness of …

The cellular microstructure of periodic architected materials can be enriched by local
intracellular mechanisms providing innovative distributed functionalities. Specifically, high …

Nonlinear metamaterials exhibit unique features allowing for wave manipulation. Despite
the increasing attention received, the underlying physical mechanisms and the evolution …

This study proposed a square-grid structure (SGS) attached with inertial amplification
mechanisms (IAMs) to obtain a better vibration isolation effect with low frequency and wide …

The present work reveals the synergistic dependence of the dynamic behaviors on the
amplitude and the frequency of an input acoustic wave for a driven granular chain. The …

An acoustic wave asymmetric propagation is implemented by a conical granular chain here.
The chain size is gradually changed interacting via Hertzian contacts. Theoretical modeling …

A 2D metamaterial cellular system inspired by lightweight honeycombs and spider webs is
investigated. The hexagonal cells of the honeycomb act as hosting substructures for spider …

In recent years, phononic material-based diodes or “phononic diodes” have been explored
to enable nonreciprocal wave propagation for novel applications such as unidirectional …
