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 …

Artificial intelligence-based algorithms are becoming essential tools in materials science-
related fields because of their excellent functionality in reflecting physics in the training …

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 …

As a branch of auxetics, the re-entrant hexagonal honeycomb has many superior
mechanical performances. However, most research focused on two-dimensional (2D) re …

Two-dimensional phononic metamaterials, consisting of plates with resonant cylinders, can
significantly attenuate waves by opening a subwavelength bandgap, though their …

An auxetic metamaterial composed of novel re-entrant unit cells was proposed. The new re-
entrant structure was constructed by adding wedge-shaped parts to the conventional re …

Novel 3D printed square auxetic tubular lattice (SATL) structures were designed, fabricated
and investigated. Their mechanical properties were examined by the finite element method …

Auxetic materials could exhibit desirable mechanical properties, eg, fracture resistance,
shear resistance and energy dissipation due to their unique deformation characteristics …
