Dealing with foam structures, some kinds of computer simulations require accurate volumetric models for high quality results. Those simulations require a large computational effort. For simplification often less complex models like beam models are used. The present work analyses the differences of effective elastic properties between accurate volumetric models and corresponding beam models of a Kelvin cell. Furthermore, the influence of certain foam geometry details on the elastic properties beside the relative density is shown. Dealing with ceramic open‐cell foams, some kinds of computer simulations require accurate volumetric models for high quality results. Due to large computational effort, less complex models like beam models are often used. The present work analyses differences of effective elastic properties between both models of a Kelvin‐cell and the influence of certain geometry details beside relative density.
