It is known that in the design of quieter mechanical systems, vibration and noise control play
important roles. Recently, acoustic black holes have been effectively used for structural …

In the recent decade, there are increasing numbers of reported studies on the use of
acoustic black hole (ABH) effects for the dam** of flexural vibrations in engineering …

The acoustic black holes (ABH) with the power-law profile are applied in many fields, such
as vibration control, energy collection, etc. It is widely known that the ABH only works above …

Vibration dam** in a thin structure can be effectively achieved by using an acoustic black
hole (ABH), which is a straight wedge-shaped structure with power-law profile. However, it is …

A truthful description of the energy transport process is vital for the understanding of the
Acoustic Black Hole (ABH) effect and its applications. One of the parameters, which can …

An acoustic black hole (ABH) structure has a gradual impedance gradient due to the
thickness of the section decreasing as a power law, which shows excellent wave gathering …

The ideal acoustic black hole (ABH) can achieve wave gathering and zero reflection of
elastic waves. In practice, ABHs have to be truncated, limiting their application in lower …

In recent years the concept of the acoustic black hole (ABH) has been developed as an
efficient, passive, lightweight absorber of bending waves in beams and plates. ABHs are …

Acoustic black hole (ABH) efiect utilizes the gradient variance of the structural conflguration
or material properties to diminish wave velocity in the structure. The wave velocity decreases …

This paper studies the bandgap properties and wave attenuation mechanisms of periodic
beams embedded with a combination of acoustic black holes (ABHs) and local resonators …
