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

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 many potential applications due to their counter-
intuitive deformation behavior and desirable mechanical properties. However, auxetic …

Once merely ancient arts, origami (ie, paper folding) and kirigami (ie, paper cutting) have in
recent years also become popular for building mechanical metamaterials and now provide …

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

The review outlines modern trends in theoretical developments, novel designs and modern
applications of sandwich structures. The most recent work published at the time of writing of …

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 …

Origami, the ancient Japanese art of paper folding, is not only an inspiring technique to
create sophisticated shapes, but also a surprisingly powerful method to induce nonlinear …

It is a challenging task to advance the excellent strength and structural performance of
sandwich structures, while continuing to reduce the weight and cost parameters. Thousands …

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 …
