The ability to significantly change the mechanical and wave propagation properties of a
structure without rebuilding it is currently one of the main challenges in the field of …

This paper presents dispersive behaviors and band gap characteristics of the multi-scale
periodic composite plate reinforced with grapheme platelets (GPLs) and fibers. The plate …

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 …

Phononic crystals have garnered considerable attention in recent years for their unique
band-gap properties, which can effectively manipulate the propagation of acoustic and …

Piezoelectric metamaterial beams have received enormous research interest for the
applications of vibration attenuation and/or energy harvesting in recent years. This paper …

Manipulating the dispersive characteristics of vibrational waves is beneficial for many
applications, eg, high-precision instruments. architected hierarchical phononic materials …

A new phononic crystal with the graded supercell configuration is proposed to broaden the
Bragg scattering band gaps. The graded structural design can merge adjacent multiple band …

This paper employs and develops the exact wave-based vibration analysis approach to
investigate the propagation properties of a designed finite lightweight locally resonant (LR) …

A proposed force sensor contains a one-dimensional periodic superlattice and piezoceramic
wave generator–receiver pair. For force sensing, the strain induced by an applied force in …
