Being messy on the inside keeps metamaterials from folding under stress

Author: Maria Temming / Source: Science News

DAMAGE CONTROL Metamaterials with internal lattices containing regions with different sizes, types or orientations of crystal structure (divvied up by yellow lines in the illustration above) could be more durable than materials with neat and tidy designs.

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.

Materials scientist Minh-Son Pham of Imperial College London…
