Splet01. dec. 1998 · The mechanical properties of cellular solids, or solid foams, is affected by “imperfections” such as wavy distortions of cell walls, variations in cell wall thickness, non-uniform cell shape, etc. The present paper is focused mainly on elastic stiffnesses of closed cell cellular solids. A “perfect” model is first discussed and shown to predict the behavior … Splet25. jul. 2016 · In this study, the theory of diametral compression is first refined to demonstrate that the relevant mechanical properties of ductile and cellular solids (i.e., …
Splet25. apr. 2016 · The mechanical behaviors of cellular solids depend on the properties of their parent material, the relative density, and their microstructure, as presented by Gibson and Ashby [ 1 ]. Honeycombs can exhibit a negative Poisson’s ratio if the cells in plane have an inverted bow-tie shape [ 2, 3 ]. Splet01. jan. 1998 · Cellular solids having (a) regular hexagonal cells, (b) equilateral triangular cells, (c) square cells, and (d) Voronoi cells. The effective moduli of cellular solids …
