Theory of Truncation Resonances in Continuum Rod-Based Phononic Crystals with Generally Asymmetric Unit Cells

Hasan B. B. Al Ba'ba'a et al.

Summary: This paper investigates the vibrational spectrum of finite phononic crystals in the form of one-dimensional rods and explains the factors that contribute to the origination of truncation resonances. By identifying a unit cell symmetry parameter, a family of finite phononic rods is defined. A transfer matrix method is utilized to derive closed-form expressions of the characteristic equations governing the natural frequencies and decipher the truncation resonances. This study establishes concrete connections between the localized vibrations, boundary conditions, and the configuration of the truncated chain, providing tools for predicting, tuning, and selectively designing truncation resonances.

Tailoring Structure-Borne Sound through Bandgap Engineering in Phononic Crystals and Metamaterials: A Comprehensive Review

Mourad Oudich et al.

Summary: In solid state physics, a bandgap refers to a range of energies where no electronic states can exist. This concept has been extended to classical waves, giving rise to photonic and phononic crystals. In elastic waves, bandgaps are found in materials with periodic alternating mechanical properties, leading to the development of elastic metamaterials and phononic crystals. The rise of topological insulators and the advancement of additive manufacturing have further expanded the functionalities of these manmade materials.

Widening, transition and coalescence of local resonance band gaps in multi-resonator acoustic metamaterials: From unit cells to finite chains

A. Stein et al.

Summary: This paper investigates the behavior of acoustic metamaterials with multiple resonating elements, showing how different configurations of resonators can be used to expand the frequency range of band gaps, enabling a wider range of wave propagation profiles. The study develops analytical expressions for multi-resonator metamaterials, revealing the mechanisms behind band gap widening and dispersion transitions in parallel resonator metamaterials, as well as the potential for collapsing solutions of acoustic and optical bands in metamaterials with dual-periodic super cells.

Tunable dissipation in elastic metamaterials via methodic reconfiguration of inertant mechanical networks

A. Aladwani et al.

Summary: Elastic metamaterials offer transformative solutions in structural mechanics by exploiting their unique capabilities in wave propagation and control. This study comprehensively analyzes the influence of different configurations of a hierarchical mechanical network on the response, bandgap characteristics, and emergent dissipation. The authors demonstrate the significant roles played by network components, architecture, and damping placement using examples of locally resonant flexural beams. The presented framework enables a direct comparison with finite metamaterial counterparts and provides insights for tailoring efficient damped responses for specific applications.
