Abstract
AbstractThe cover picture shows some results of simulated metal foam structures. To learn more about the structure of random foams, read the article by Andrew M. Kraynik on page 900.Surface Evolver models of soap froth with a wide range of cell‐size distributions are used to investigate random cellular morphology. Geometric properties of foams and foam cells are analyzed. A simple, accurate theory relates the total suface area of foam to the cell‐size distribution. The total surface area is approximately equal to the total edge length when both quantities are scaled by average cell volume. Voronoi structures are significantly different from foams, which raises questions over their use for predicting structure‐property relationships.
