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

Dynamic compressive behaviour of cellular materials is crucial to their applications in
energy absorption, ballistic mitigation and blast/impact protection. The recent research …

Auxetic metamaterials with excellent mechanical properties have attracted considerable
attention for use in various applications, especially for energy-absorption. In this work, novel …

Equivalent sandwich panels composed of auxetic and conventional honeycomb cores and
metal facets are analysed and compared for their resistance performances against impulsive …

Honeycombs with re-entrant (RE) unit cells were found to have negative Poisson's ratios
(NPRs) and enhanced energy absorption capabilities than regular hexagon honeycombs …

A series of novel bionic honeycombs (bio-honeycombs) are proposed by incorporating the
microstructure of the beetle elytra intersection unit into the regular hexagonal honeycomb …

In order to improve the energy absorption capacity of the honeycomb, a combined auxetic
honeycomb is designed in this paper. By using the double-inclined walls replacing the …

Auxetic honeycombs exhibit low weight, shear stiffness, and excellent energy absorption
capacity and thus have great potential for achieving the requirements of crashworthiness …

This paper aims to develop lightweight high-performance auxetic structures for protective
applications such as blast and impact energy absorption. In this study, novel auxetic …

This work presents a comparative study on the reliability of auxetic (re-entrant honeycomb)
and non-auxetic (diamond lattice and conventional honeycomb) lattice composites. The …
