Vibration and sound control is critical to many practical engineering systems in order to
minimise the detrimental effects caused by unavoidable vibrations and noises …

In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

Circular cam-roller (CCR) quasi-zero stiffness (QZS) vibration isolators have been
extensively studied. As the CCR isolator can only achieve low stiffness in a very small range …

Abstract Quasi‐zero‐stiffness (QZS) isolators of high‐static‐low‐dynamic stiffness play an
important role in ultra‐low frequency vibration mitigation. While the current designs of QZS …

This paper presents an innovative design of the quasi-zero stiffness (QZS) isolator with three
pairs of oblique springs. Formulations of stiffness are firstly derived and parameter study is …

Despite their engineering significance, locally resonant metamaterials are facing the
challenge to cope with the need for broad-range band gap adjustment at low-frequencies …

An innovative Poisson's ratio (PR) sign-switching stiffness-changing mechanical
metamaterial with potential applicability in automotive and construction industries is …

This paper develops a novel type of two-dimensional (2D) locally resonant (LR)
metamaterials with quasi-zero-stiffness (QZS) property both in the horizontal and vertical …

Mechanical metamaterials exhibit some superior mechanical properties such as ultrahigh
strength-to-weight ratio, negative bulk-modulus, negative stiffness, negative mass-density …

A novel metamaterial beam with embedded quasi-zero-stiffness (QZS) resonator is
proposed to realize wave attenuation in very low-frequency band gaps. The configuration of …
