Foam Structures with a Negative Poisson's Ratio.

R Lakes (1987)

A novel foam structure is presented, which exhibits a negative Poisson's ratio. Such a material expands laterally when stretched, in contrast to ordinary materials.

3D soft metamaterials with negative Poisson's ratio.

Sahab Babaee, Jongmin Shim, James C Weaver … (2013)

Buckling is exploited to design a new class of three-dimensional metamaterials with negative Poisson's ratio. A library of auxetic building blocks is identified and procedures are defined to guide their selection and assembly. The auxetic properties of these materials are demonstrated both through experiments and finite element simulations and exhibit excellent qualitative and quantitative agreement. © 2013 WILEY-VCH Verlag GmbH & Co.
