The present study is concerned with the macroscopic material response of solid foams and other highly microheterogeneous solids in the finite strain regime. For the homogenization of the microstructure, a strain energy based procedure is proposed. This procedure is subsequently employed for the analysis of the macroscopic behavior of two‐dimensional model foams. Distinct effects of a deformation induced cell wall re‐alignment are observed which cannot adequately be included in pure small strain analyses.
