摘要: Auxetic materials are gaining practical interest for their unusual and sometimes extreme mechanical response. The process of modeling these so far has highlighted a number microstructural properties that key to materials. However models often rely on the assumption homogeneity order within Practically, homogeneous auxetic material such as foam is unlikely be manufactured. This work seeks analyze effect fluctuations microstructure material. Numerical results show in an granular substance analytical indicates relation between microscale elastic moduli general
