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

As a result of their mechanical characteristics, biological structures often provide inspiration
for the development of high-performance mechanical structures. Nevertheless, traditional …

With the swift advancement of aerospace, shipbuilding and engineering, the significance of
sandwich structures with cellular cores is becoming increasingly prominent due to their multi …

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

Auxetics are a class of structural metamaterials with a negative Poisson's ratio. In
comparison to conventional structures, auxetic structures are proven to exhibit several …

Achieving superior reusable energy absorption and mitigation properties under repeated
impact loadings with high strain rates, yet maintaining the lightweight design feature, is still a …

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 …

Innovative honeycomb-based structures have been paid substantial attention in recent years
due to their superb mechanical performances and specific functions. The presented study …

It is a challenging task to advance the excellent strength and structural performance of
