Auxetic foams counter-intuitively expand (shrink) under stretching (compression). These
foams can exhibit superior mechanical properties such as resistance to shear and …

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) …

Ultralight, ultrastrong, and supertough graphene aerogel metamaterials combining with multi-
functionalities are promising for future military and domestic applications. However, the …

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 …

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 …

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 …

Recent advances in lithography technology and the spread of 3D printers allow us a facile
fabrication of special materials with complicated microstructures. The materials are called …

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 …
