Elasticity and rheology of auxetic granular metamaterials

Proceedings of the National Academy of Sciences
The flowing, jamming, and avalanche behavior of granular materials is satisfyingly universal and vexingly hard to tune: A granular flow is typically intermittent and will irremediably jam if too confined. Here, we show that granular metamaterials made from particles with a negative Poisson’s ratio yield more easily and flow more smoothly than ordinary ...

A unified spatial Poisson’s ratio design method (SPRDM) for 3D Poisson’s ratio metamaterials based on a minimal chiral structure

Materials & Design
Poisson’s ratio metamaterials exhibit unconventional deformation behaviors enabled by architected internal geometries. While numerous planar auxetic and related designs have been reported, the systematic generation and classification of spatial Poisson’s

A critical review on the application of machine learning in supporting auxetic metamaterial design

JPhys Materials
The progress of machine learning (ML) in the past years has opened up new opportunities to the design of auxetic metamaterials. However, successful implementation of ML algorithms remains challenging, particularly for complex problems such as domain ...

On anisotropic versions of three-dimensional pentamode metamaterials

New Journal of Physics, 2013
Pentamode materials are artificial solids with elastic properties that approximate those of isotropic liquids. The corresponding three-dimensional mechanical metamaterials or ‘meta-liquids’ have recently been fabricated.
