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

In the past decade, mechanical metamaterials have garnered increasing attention owing to
its novel design principles which combine the concept of hierarchical architecture with …

Here, we present the in-plane energy absorption characteristics of modified re-entrant
auxetic honeycombs realized via fused filament fabrication in conjunction with parametric …

Auxetic materials have excellent mechanical properties, eg, indentation resistance, shear
resistance, fracture toughness and energy absorption. However, the stiffness of auxetics is …

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

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 …

Mechanical metamaterials with unique micro-architectures possess excellent physical
properties in terms of stiffness, toughness, vibration isolation, and thermal expansion …

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 …
