Abstract

A hyperelastic constitutive model for compressible materials undergoing large deformations is introduced from the evaluation, by homogenization, of the strain energy density function of periodic porous rubber composites. For infinitesimal deformations the proposed material model remains unidentifiable from the Blatz-Ko one, but it is shown that, at higher stretching levels, these models differ substantially
