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

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

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

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

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 …
