Cellular Solids: Structure and Properties
Lorna J. Gibson,Michael F. Ashby +1 more
TL;DR: The linear elasticity of anisotropic cellular solids is studied in this article. But the authors focus on the design of sandwich panels with foam cores and do not consider the properties of the materials.
Journal ArticleDOI
Foam structures with a negative poisson's ratio
TL;DR: A novel foam structure is presented, which exhibits a negative Poisson's ratio, and such a material expands laterally when stretched, in contrast to ordinary materials.

The mechanics of three-dimensional cellular materials
Lorna J. Gibson,Michael F. Ashby +1 more
TL;DR: In this paper, the mechanical properties of two-dimensional cellular materials, or honeycombs, are analyzed and compared with experiments, in terms of bending, elastic buckling and plastic collapse of the beams that make up the cell walls.

Models for the elastic deformation of honeycombs
I.G. Masters,Kenneth E. Evans +1 more
TL;DR: In this paper, a theoretical model was developed for predicting the elastic constants of honeycombs based on the deformation of the honeycomb cells by flexure, stretching and hinging, which can be used to derive expressions for the tensile moduli, shear moduli and Poisson's ratios.
