Phononic crystals (PCs) and metamaterials (MMs) can exhibit abnormal properties, even far
beyond those found in nature, through artificial design of the topology or ordered structure of …

Instabilities in solids and structures are ubiquitous across all length and time scales, and
engineering design principles have commonly aimed at preventing instability. However …

We report a new class of tunable and switchable acoustic metamaterials comprising
resonating units dispersed into an elastic matrix. Each resonator consists of a metallic core …

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

In this paper, we present a theoretical model for the analysis of large magneto-deformation
and the anti-plane shear wave bandgaps in 2D periodic two-phase hard magnetic soft …

Multistable mechanical metamaterials are materials that have multiple stable configurations.
The geometrical changes caused by the transition of the metamaterial from one stable state …

Emerging interest to synthesize active, engineered matter suggests a future where smart
material systems and structures operate autonomously around people, serving diverse roles …

Applying hierarchical cuts to thin sheets of elastomer generates super-stretchable and
reconfigurable metamaterials, exhibiting highly nonlinear stress-strain behaviors and …

The proposed structure comprises an array of elastomeric helices that can be easily
stretched in the axial direction (see Figure 1). In the undeformed configuration the helices …

Controlling band gaps of phononic crystals in real time through external stimuli (eg
mechanical loadings, electric fields, and magnetic fields) shows potential applications in …
