Honeycombs are ultra-light materials with outstanding mechanical properties, which mainly
originate from their unit cell configurations rather than the properties of matrix materials …

Mechanical metamaterials are engineered materials with unconventional mechanical
behavior that originates from artificially programmed microstructures along with intrinsic …

Lightweight materials and structures have attracted tremendous interests for their compelling

Auxetic foams counter-intuitively expand (shrink) under stretching (compression). These
foams can exhibit superior mechanical properties such as resistance to shear and …

Auxetic materials are a class of mechanical metamaterials. They exhibit lateral expansion
under tension, and lateral contraction under compression. Such metamaterials have …

The rapid progress of advanced manufacturing, multidisciplinary integration and artificial
intelligence has ushered in a new era of technological development in the design of …

Auxetic materials and structures have many potential applications due to their counter-
intuitive deformation behavior and desirable mechanical properties. However, auxetic …

Here, we present the in-plane energy absorption characteristics of modified re-entrant
auxetic honeycombs realized via fused filament fabrication in conjunction with parametric …

Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …
