The present study provides an analytical probabilistic approach for the homogenization of hyperelastic solid foams with irregular microstructure. The scheme is based on the multiple analysis of a randomized representative volume element in conjunction with a stochastic evaluation of the results in terms of the stress mean values and the corresponding standard deviations defining the scatter band widths.
