The law of reciprocity in acoustics and elastodynamics codifies a relation of symmetry
between action and reaction in fluids and solids. In its simplest form, it states that the …

Phononic materials are periodically arranged building blocks in the form of material
properties, geometries, and/or boundary conditions. This synthetic architecture makes …

Phononic crystals (PnCs) and acoustic metamaterials (AMMs) are artificially architected
materials endowed with the capabilities of wave manipulation. This review specifically …

The on-demand control of supratransmission is of fundamental importance for practical
applications in areas such as energy transmission. The occurrence of supratransmission is …

This paper reports the dynamic effects leveraged into one-dimensional metastructures by
Duffing-and Nonlinear Energy Sink (NES)-type piezoelectric attachments. The versatility of …

In this research, we investigate in-depth the nonlinear energy transmission phenomenon in
a metastable modular metastructure and develop efficient tools for the design of such …

We study the phenomenon of supratransmission (that is, the sudden transmission of energy
above a sharp threshold amplitude of periodic boundary excitations) on an N-particle one …

This paper reports dynamical effects in one-dimensional locally resonant piezoelectric
metastructures leveraged by nonlinear electrical attachments featuring either combined …

In this work, we introduce a spatially discrete model that is a modification of the well-known α-
Fermi–Pasta–Ulam chain with damping. The system is perturbed at one end by a harmonic …

The nonlinear supratransmission phenomenon in a Fermi-Pasta-Ulam (FPU) diatomic lattice
with two forbidden bands is investigated. Using a decoupling ansatz for the motion of the two …
