报告摘要：Cellular materials are widely used in different engineering applications. More importantly, our human body is primarily functioned by different types of nano-structured hierarchical cellular materials.   This presentation will give a brief introduction about the size-dependent and tunable elastic and geometrical properties of nano-structured and hierarchical cellular materials.  All the independent elastic properties are obtained as the functions of the solid volume fraction for different types nano-structured hierarchical honeycombs and open-cell foams.
