Bio-inspired materials have shown to have outstanding mechanical properties over man-made materials and are becoming of increasing interest in many fields of practical applications. Additionally, recent advances in materials and fabrication technologies allow for the design and fabrication of micro- and nano-scale structures to serve as cellular units in macro-scale materials. The mechanical behaviors of cellular solids, including stiffness and strength, can be tuned by simply tailoring the underlying geometry of the structure. In this paper the answer to the following research question is investigated: Can seemingly different bio-inspired geometries of cellular solids result in similar mechanical behaviors? Specifically, the effects of geometry on the compressive deformation responses of multiple bio-inspired periodic cubic cellular structures at macro scale are investigated both through physical tests and FE simulations of 3D printed specimens. The paper outlines standardization of specimens and tests for such a study. Additionally, a $1 recognizer based classification process is used on curves representing compressive deformation behaviors of different bio-inspired geometries to cluster them into same group.
