TLDR
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.Abstract:
The mechanical properties (linear and nonlinear elastic and plastic) of two-dimensional cellular materials, or honeycombs, are analysed and compared with experiments. The properties are well described in terms of the bending, elastic buckling and plastic collapse of the beams that make up the cell walls.read more

Indentation resistance of brittle auxetic structures: Combining discrete representation and continuum model
Z. Li,K.F. Wang,Binshen Wang +2 more
TL;DR: In this paper, the authors investigated the indentation resistance of the auxetic/non-auxetic honeycomb ceramics layer by combining a discrete numerical representation and a continuum analytical model.

Porous exfoliated poly(ε-caprolactone)/clay nanocomposites: Preparation, structure, and properties
Oana M. Istrate,Biqiong Chen +1 more
TL;DR: Porous biodegradable poly(e-caprolactone) (PCL)/clay nanocomposites were prepared by incorporating a blowing agent into the galleries of an organoclay, followed by mixing the pretreated organocollay and PCL to give partially intercalated and exfoliated nanocompositionites and subsequently degrading the blowing agent in situ to increase the exfoliation degree in the porous nan composites as discussed by the authors.

Theory of elasticity
TL;DR: The theory of the slipline field is used in this article to solve the problem of stable and non-stressed problems in plane strains in a plane-strain scenario.
Book
On Growth and Form
TL;DR: This book is an application of some of the concepts of physical science and sundry mathematical methods to the study of organic form and is like one of Darwin's books, well-considered, patiently wrought-out, learned, and cautious.

The Elastic Constants of a Solid containing Spherical Holes
TL;DR: In this article, a self-consistent method for the estimation of the shear modulus and the bulk modulus is proposed, where each hole is surrounded by a spherical shell of real material, and the reaction of the rest of the material is estimated by replacing it by equivalent homogeneous material.
