Guided waves, elastic waves propagating through bounded structures, play a pivotal role in
various applications, including ultrasonic non-destructive testing and structural health …

In this letter, it is suggested to attach acoustic black holes (ABHs) on a base beam with
gradient parameters for wave attenuation in ultrawide bands. Three types of metabeams …

In this work we first propose a wave and Rayleigh–Ritz method (WRRM) to analyze the
vibrations of periodic systems. It is well-known that one of the main difficulties of the …

Acoustic black holes (ABHs) have been found to exhibit desirable damping characteristics
for vibration attenuation of thin-walled structures. However, up until now, no research has …

Acoustic black holes (ABHs) attract increasing attention in the field of vibration suppression,
sound radiation control and energy harvesting. Though the ABH effect usually works well in …

This paper presents a modified add-on strategy to reduce the transverse vibration of beam
structures using multiple acoustic black hole dynamic vibration absorbers (ABH-DVAs). The …

While acoustic black holes (ABHs) are well-known inefficient at low frequencies. However,
attaching periodic local resonators to form a metamaterial ABH (MMABH) plate could be …

Damping mechanical resonances is a formidable challenge in an increasing number of
applications. Many passive damping methods rely on using low stiffness, complex …

Acoustic black holes (ABHs) have been shown very efficient to reduce sound radiation in the
air. However, their underwater performance is not clear. In this paper, we consider a Mindlin …

Rotating disk-drum coupled structures are commonly employed in large rotating machines.
They are prone to have vibration issues caused by their decreasing thickness to meet …
