     solid foams are novel materials that have found numerous applications in the construction of light, stiff structures during the past few decades. at the micro-level, solid foams possess a cellular structure that comprises either closed or open cells. open-cell foams, which are the concern of this study, are described as a network of inter-connected struts (or ligaments) with beam-like action. in order to assess their macroscopic mechanical behavior one needs to account for the micro-structural mechanisms inherent in such materials. homogenization methods provide a natural solution by linking the response of each material point on the macro-scale to the response of a representative portion of the microstructure, namely rve, on the micro-scale. current study employs a version of these methods to study the effect of cell shape (cell morphology) variation on the macroscopic uniaxial compressive response of open-cell foams.
