Vibration analysis of porous sandwich beam reinforced by graphene platelets/graphene origami auxetic metamaterials using sinusoidal shear deformation theories in thermal environment

Discover Applied Sciences
The stiffness and vibration characteristics of the face sheets strongly influence the mechanical performance of sandwich beams. Reinforcing these layers with advanced nanomaterials has been demonstrated to enhance stiffness and effectively suppress ...

Influence of polymer properties on the mechanical behaviour of 3D-printed auxetic metamaterials and honeycomb structures under bending load

Manufacturing Review
Metamaterials with auxetic behaviour have great potential for a new generation of load-bearing lightweight sandwich structures due to their outstanding energy absorption capabilities.

Ideal isotropic auxetic networks from random networks

, 2019
Auxetic materials are characterized by a negative Poisson's ratio, $\mathrm{\nu}$. As the Poisson's ratio becomes negative and approaches the lower isotropic mechanical limit of $\mathrm{\nu = -1}$, materials show enhanced resistance to impact and shear,

A seamless auxetic substrate with a negative Poisson’s ratio of −1

Nature Communications
Auxetic metamaterials are a unique class of materials or structures with a negative Poisson’s ratio and a wide array of functionalities. However, their inherent porosity presents challenges in practical applications.

Auxetic granular metamaterials

Granular materials are materials that consist of many compartments. The collective behaviour of these smaller grains is typically very different from the behaviour of the individual grains. A clear sample is sand. The individual sand grains are solid. On the beach the grains support weight like a solid.
