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

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

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

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

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

Over the past several decades, a noticeable amount of research efforts has been directed to
minimising injuries and death to people inside a structure that is subjected to an impact …

In this paper, rigid polyurethane (PU) foam was filled into hollow auxetic tube for enhancing
the energy absorption. The rigid PU foams and stainless-steel auxetic tube with different …

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

ABSTRACT A novel type of tubular structure with negative Poisson's ratio based on gyroid-
type triply periodic minimal surfaces (TPMSs) is proposed in this study. This work is an …

We combine 3D printing technique, numerical analysis, and experiments to design a new
class of sandwich composites that exhibit various bending behaviors. These programmed …
