Metamaterials are artificial materials designed to exhibit effective material parameters that
go beyond those found in nature. Composed of unit cells with rich designability that are …

In the past decades, many mechanical metamaterials with uncommon static properties have
been reported. On the other hand, mechanical metamaterials possessing extraordinary …

Metamaterials with artificially designed architectures are increasingly considered as new
paradigmatic material systems with unusual physical properties. Here, we report a class of …

Vibration control is an overwhelmingly concerned issue that exists in many industrial fields
such as machinery, aerospace and civil engineering. Indeed, in terms of energy perspective …

The mechanical response of interpenetrating phase composites (IPCs) with stochastic
spinodal topologies is investigated experimentally and numerically. Model polymeric …

Various strategies have been proposed in recent years in the field of mechanical
metamaterials to widen band gaps emerging due to either Bragg scattering or to local …

Additive manufacturing (AM) is a revolutionary technology that enables production of
intricate structures while minimizing material waste. However, its full potential has yet to be …

Unlike well-studied locally resonant (LR) metamaterials with a periodic array of identical
resonators,'graded'LR metamaterials consist of an array of resonators with a spatially …

Through finite element analysis and a 3D printing assisted experimental study, we
demonstrate a design of mechanical metamaterials for simultaneous mechanical wave …

Hierarchy provides unique opportunities for the design of advanced materials with superior
properties that arise from architecture, rather than from constitutive material response …
