In this work, the wave propagation properties of lightened bioinspired composite materials
are investigated. A new lightened nacre-like microstructure is proposed demonstrating that …

The topologically protected elastic wave transport in hierarchical metamaterials for the in-
plane mode and out-of-plane mode is investigated in this work. First of all, the influence of …

Hierarchical structures with constituents over multiple length scales are found in various
natural materials like bones, shells, spider silk and others, all of which display enhanced …

We experimentally and numerically investigate elastic wave propagation in a class of
lightweight architected materials composed of hollow spheres and binders. Elastic wave …

Sound absorption for a broad frequency range requires sound dissipation. The mechanics of
acoustic metamaterials for non-dissipative applications has been extensively studied, but …
