Abstract

<abstract abstract-type="graphical" xml:lang="en" id="adma201501708-abs-0001"> <title> <x xml:space="preserve">Abstract</x> </title> <p> <bold>3D printing and numerical analysis</bold> are combined to design a new class of architected materials that contain bistable beam elements and exhibit controlled trapping of elastic energy. The proposed energy‐absorbing structures are reusable. Moreover, the mechanism of energy absorption stems solely from the structural geometry of the printed beam elements, and is therefore both material‐ and loading‐rate independent. <graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgj2c0mkjjv" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></p> </abstract>
