Porous/multi-cell structures are widely used in practical engineering due to their excellent
energy absorption capacity and lightweight. In recent decades, as an important member of …

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) …

This work describes the low-velocity impact behavior of composite sandwich panels with
different types of auxetic (negative Poisson's ratio) and non-auxetic prismatic core structures …

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

Mechanical metamaterials can be defined as a class of architected materials that exhibit
unprecedented mechanical properties derived from designed artificial architectures rather …

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 metamaterials have attracted increasing attention due to their exceptional
mechanical properties. However, the critical parameters of mechanical response and …

Material properties can be tailored through modification of their geometry or architecture.
With this concept, a lot of smart materials, metamaterials, and smart structures have been …
