This broad review summarizes recent advances and “hot” research topics in nanophononics
and elastic, acoustic, and mechanical metamaterials based on results presented by the …

Phononic crystals (PnCs) control the transport of sound and heat similar to the control of
electric currents by semiconductors and metals or light by photonic crystals. Basic and …

Seismic metamaterial (SM) has lately received significant attention in the field of vibration
isolation and damping due to its wave manipulation and bandgap properties. However, the …

Auxetic materials could exhibit desirable mechanical properties, eg, fracture resistance,
shear resistance and energy dissipation due to their unique deformation characteristics …

The advancement in electromagnetic metamaterials, which commenced three decades ago,
experienced a rapid transformation into acoustic and elastic systems in the forms of …

The energy of ground-born vibration is transported mostly by surface waves. Therefore,
engineered structures which absorb externally applied energy and improve structural …

Mechanical metamaterials, also known as architected materials, are rationally designed
composites, aiming at elastic behaviors and effective mechanical properties beyond ('meta') …

The adverse effect of mechanical vibration is inevitable and can be observed in machine
components either on the long-or short-term of machine life-span based on the severity of …

With the rapid development of high speed rail system, ground vibration mitigation solutions
are desperately needed. Based on the concepts of phononic crystals, seismic metamaterial …

The properties of bandgaps (BGs) for manipulating elastic/acoustic waves are highly
determined by the spatial distribution of materials in the primitive unit cell. In this work, the …
