Among various strategies developed for the attenuation of noise and vibration in mechanical
structures, piezoelectric shunt damping, which consists in connecting piezoelectric …

Achieving vibration and/or wave attenuation with locally resonant metamaterials has
attracted a great deal of attention due to their frequency dependent negative effective mass …

Elastic metamaterials have been extensively investigated due to their significant effects on
controlling propagation of elastic waves. One of the most interesting properties is the …

As an important tool for monitoring the marine environment, safeguarding maritime rights
and interests and building a smart ocean, underwater equipment has developed rapidly in …

In this paper, a tunable beam-type metamaterial composed of elastic base beams and
periodically arrayed active beam-type resonators is designed and analyzed theoretically …

The ability to control elastic wave propagation at a deep subwavelength scale makes locally
resonant elastic metamaterials very relevant. A number of abilities have been demonstrated …

This paper studies sound transmission loss (STL) of a metamaterial thin plate consisting of
periodic subwavelength arrays of shunted piezoelectric patches bonded to the two surfaces …

We present an electromechanical modeling framework and a detailed numerical
investigation for the design and analysis of piezoelectric metamaterial beams whose unit …

A great deal of research has been devoted to controlling the dynamic behaviors of phononic
crystals and metamaterials by directly tuning the frequency regions and/or widths of their …

This paper explores a new approach to reducing the interior noise of one vehicle body
through the flexural wave bandgap. The phononic crystal is designed by attaching the …
