Traditional body-centered cubic (BCC) lattice metamaterials exhibit structural deficiencies including geometric discontinuity at cell connections and pronounced stress concentration at nodal regions, ...

Herein new lattice unit cells with buckling load 261–308% higher than the classical octet unit cell were reported. Lattice structures have been widely used in sandwich structures as lightweight core.
