Strategically architected elastomeric materials constrained near critical points yield extreme impact energy absorption for structures in which they are embedded. This image includes high-speed video stills of drop experiments conducted to quantify the impact energy attenuation provided by specimens for the shells into which the specimens are inserted. Architected and strategically constrained specimens (bottom row) more greatly suppress impact energy than the bulk material itself (top row). Further details can be found in the article by Ryan Harne and co-workers on page 1871.
