Wave Propagation in Sandwich Panel with Auxetic Core

Auxetic cellular solids in the forms of honeycombs and foams have great potential in a diverse range of applications, including as core material in curved sandwich panel composite components, radome applications, directional pass band filters, adaptive and deployable structures, filters and sieves, seat cushion material, energy absorption components, viscoelastic damping materials and fastening...

A review on auxetic structures and polymeric materials

Auxetic polymeric materials are a special kind of materials that exhibit negative Poisson’s ratio (NPR) effect. They get fatter when stretched and thinner when compressed. Auxetic behavior is a scaleindependent property which can be achieved at different structural levels from molecular to macroscopic levels. The internal structure of material plays an important role in obtaining auxetic effect...

Tuning the Performance of Metallic Auxetic Metamaterials by Using Buckling and Plasticity

Metallic auxetic metamaterials are of great potential to be used in many applications because of their superior mechanical performance to elastomer-based auxetic materials. Due to the limited knowledge on this new type of materials under large plastic deformation, the implementation of such materials in practical applications remains elusive. In contrast to the elastomer-based metamaterials, me...

Effects of size and surface on the auxetic behaviour of monolayer graphene kirigami

Graphene is an active element used in the design of nano-electro-mechanical systems (NEMS) owing to its excellent in-plane physical properties on mechanical, electric and thermal aspects. Considering a component requiring negative Poisson's ratio in NEMS, a graphene kirigami (GK) containing periodic re-entrant honeycombs is a natural option. This study demonstrates that a GK with specific auxet...
