Abstract: The micro-structure of low density open-cell foams can be modeled by Voronoi tessellation. By using this random geometric model, the modulus of low density open-cell foams is calculated. The influences of relative density and the shape of strut cross-section on the modulus are also discussed at the same time. The calculated results fit well with Gibson's semi-empirical model.
Key words: elastic modulus, random model, open-cell foams, Voronoi tessellation
