Lattice structures, which are also known as architected cellular structures, have been
applied in various industrial sectors, owing to their fascinated performances, such as low …

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

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

In this paper, we give a review of the state of the art in the study of mechanical
metamaterials. The very attractive property of having a microstructure capable of …

Continuous fiber reinforced thermoplastic composite (CFRTPC) auxetic honeycomb
structures were fabricated using the 3D printing technology with a specific printing path …

Honeycomb structures have been used extensively in lightweight sandwich structure and
impact energy absorption applications. Recently the research has been carried out on …

We combine 3D printing technique, numerical analysis, and experiments to design a new
class of sandwich composites that exhibit various bending behaviors. These programmed …

Auxetic materials exhibiting a negative Poisson's ratio are shown to have better indentation
resistance, impact shielding capability, and enhanced toughness. Here, we report a class of …

Auxetic materials become thicker rather than thinner when stretched, exhibiting an unusual
negative Poisson's ratio well suited for designing shape transforming metamaterials. Current …

This book discusses bulk solids that derive their mechanical properties not from those of
their base materials, but from their designed microstructures. Focusing on the negative …
