“…Metamaterials, a sub-class of cellular materials, with a periodic three-dimensional architecture, carefully engineered structure, and mechanical properties primarily dependent on their architecture rather than their constituent material, are in fact the most recent development in the ongoing quest for novel materials. They have shown their potential for blast protection [46,47] and impact energy absorption applications [48], while maintaining a relatively high stiffness and low density [49][50][51]. Additively-manufactured metamaterials with complex structures and micro scale components might revolutionize the conventional energy absorbing materials, not only due to their large densification strains and high strength to weight ratio, but also due to their shape recovery capabilities.…”

With the advent of additive manufacturing, fabrication of complex structures with high efficiency for energy absorption and blast and impact mitigation has entered a new era. In this research the role of the architecture and material properties on the static and dynamic energy absorption properties of additively-manufactured complex cellular structures out of two different materials were studied under puncture and crush tests. A finite element simulation of the unit cell was also conducted to study the effect of loading rate on the final response of the material where the results showed good agreement with the experimental observations. It is shown that the studied additively manufactured structures were able to recover their shape significantly after a major deformation due to the impact. These results show the potential of additive manufacturing as a versatile tool for creating structures with complex geometries for energy absorption.
