In this paper, we give a review of the state of the art in the study of mechanical
metamaterials. The very attractive property of having a microstructure capable of …

The emerging concept of mechanical meta-materials has received increasing attention
during the last few years partially due to the advances in additive manufacturing techniques …

Poisson's ratio had long been considered to be an intrinsic material property, confined within
a narrow domain and governed solely by the geometry of interatomic bonds. Materials with …

We create mechanical metamaterials whose response to uniaxial compression can be
programmed by lateral confinement, allowing monotonic, nonmonotonic, and hysteretic …

Background Vibration present on various levels in many engineering fields and hence
vibration mitigation has become a subject of intense study. The nonlinear vibration isolation …

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

Structures and materials absorbing mechanical (shock) energy commonly exploit either
viscoelasticity or destructive modifications. Based on a class of uniaxial light-weight …

Mechanical metamaterials have been attracting increasing attention for a wide range of
industrial applications, such as energy storage, biomedical, sensors, robotics, etc., owing to …

Acoustic metamaterials with negative constitutive parameters (modulus and/or mass density)
have shown great potential in diverse applications ranging from sonic cloaking, abnormal …

Making materials lightweight while attaining a desirable combination of mechanical, thermal,
and other physical properties is the “holy grail” of material science. Lattice materials …
