Investigation into elastic properties of anisotropic random foam model

  • In order to investigate the influence of cell microstructure anisotropy on the mechanical properties with random model, on the basis of isotropic Voronoi random foam model, anisotropic open-cell and closed-cell random foam models were established through considering cell growth rate difference. The elastic properties of these models were analyzed by the finite element method. The relation between the relative Young′s modulus of the models and the anisotropic size ratio was obtained and compared with theory predicted results; the relation between the Poisson′s ratio and the anisotropic size ratio was also obtained and compared. The results indicate that the open-cell and closed-cell random foam model can reflect the cell anisotropic mechanical properties well, and the anisotropic mechanical properties of open-cell and closed-cell foam both have relation with relative density.
