The aim of this study is to design a two-dimensional solid structure with embedded inertial
amplification mechanisms that shows an ultrawide stop band (band gap) at low frequencies …

Realizing a low-frequency and broad bandgap is extremely challenging because the lattice
constant, equivalent stiffness, and equivalent density must be taken into account in practice …

Isolating low-frequency vibrations is a challenge in engineering due to their long
wavelength. The bandgap within inertial amplification metastructures has proven to be an …

This work presents the design, manufacture, and experimental testing of a three-
dimensional twisted phononic crystal made of a single-phase material. A broad …

The study of vibrational properties in engineered periodic structures relies on the early
intuitions of Haüy and Boscovich, who regarded crystals as ensembles of periodically …

Phononic band gaps are investigated in a one-dimensional (1D) array of compliant axial to
rotary motion conversion mechanisms. To create low frequency band gaps, the effective …

Releasing the dependence of the low-frequency and broad bandgaps on low stiffness and
bulky masses has been an intractable bottleneck. Although inertial amplification is a terrific …

Mass reduction of automotive components enhances vehicles' performance and extends
their driving range. However, lightweight construction typically leads to noise and vibration …

Chiral phononic crystals (PnCs) provide unique properties not offered by conventional
metamaterial based on classic Bragg scattering and local resonance. However, it is …

Phononic structures with unit cells exhibiting Bragg scattering and local resonance present
unique wave propagation properties at wavelengths well below the regime corresponding to …
