The design of “Grain Boundary Engineered” architected cellular materials: The role of 5-7 defects in hexagonal honeycombs
Abstract
Inspired by heterogeneous structures observed in nature (graphene, insects’ eyes, and beehives), we demonstrate that topological defects in hexagonal honeycombs can enhance strength and energy absorption capacity. These defects consist of pentagon-heptagon pairs (known as 5–7 defects). Experimental studies of additive manufactured specimens and computational studies are performed on honeycomb panels that are perfectly periodic or that contain …
