Human-made metamaterials with messy internal designs may be more resistant to damage than those with neatly patterned structures.
Metamaterial lattices, usually composed of struts that form identical, repeating “unit cells,” can exhibit properties that normal solids don’t (SN: 1/19/19, p. 5). But under heavy loads, overstressed struts can collapse, and that breakage quickly splinters through the whole grid, causing it to crumble.
