Abstract  The macro-mechanical performances of foams are mainly determined by its micro-structure and the properties of cell material, so it is helpful for foam mechanical performance prediction by constructing a proper micro-mechanical foam model. According to the microstructure of real silicone rubber foams, three dimensional (3D) random spherical cell models are constructed by Matlab language and Abaqus software. Then large compressive deformations are simulated, and the young’s modulus, shear modulus, bulk modulus and Poisson’s ratios of rubber foams are calculated. The constitutive models of the foam elastic properties are performed by numerical fitting. Obtained results reveal that the random models behavior isotropy and the models are effective to predict the elastic performances of rubber foams.
