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

Different from conventional materials, materials with negative Poisson's ratios expand
laterally when stretched longitudinally. Known as 'auxetic'materials, the effect means they …

Cellular structures consist of foams, honeycombs, and lattices. Lattices have many
outstanding properties over foams and honeycombs, such as lightweight, high strength …

Materials and structures with negative Poisson's ratio exhibit a counter-intuitive behaviour.
Under uniaxial compression (tension), these materials and structures contract (expand) …

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

Rational design of artificial micro-structured metamaterials with advanced mechanical and
physical properties that are not accessible in nature materials is challenging and important …

Auxetic materials and structures have attracted increasing attention because of their
extraordinary mechanical properties. Various types of auxetic tubular structures have been …

The surge of interest in so-called “designer materials” during the last few years together with
recent advances in additive manufacturing (3D printing) techniques that enable fabrication …

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

Auxetic materials have excellent mechanical properties, eg, indentation resistance, shear
resistance, fracture toughness and energy absorption. However, the stiffness of auxetics is …
