Abstract

Cellular materials are made up of an interconnecting network of strut- or plate-like members. Natural cellular materials include wood, cancellous bone, cork, palm and leaves. Engineering cellular materials are either in the form of honeycombs, with two-dimensional, prismatic cells, or foams with three-dimensional, polyhedral cells. Natural cellular materials usually have multiple phases at multiple scales while engineering cellular materials use a single phase at a single scale.

In this paper, the efficiencies of various natural cellular materials are estimated by analyzing their behavior at various microstructural scales. The results of the analysis suggest microstructural design of hierarchically structured engineering cellular materials.
