Porous/multi-cell structures are widely used in practical engineering due to their excellent
energy absorption capacity and lightweight. In recent decades, as an important member of …

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 …

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

Rational design of artificial micro-structured metamaterials with advanced mechanical and
physical properties that are not accessible in nature materials is challenging and important …

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

Mechanical metamaterials are man-made structures with counterintuitive mechanical
properties that originate in the geometry of their unit cell instead of the properties of each …

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 …

Mechanical metamaterials can be defined as a class of architected materials that exhibit
unprecedented mechanical properties derived from designed artificial architectures rather …

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 …
