Abstract
An energy-dispersing article comprises: first and second material sheets, a first set of U-shaped rods attached at both ends to the first sheet, and a second set of U-shaped rods attached at both ends to the second sheet. The first and second material sheets are positioned in a parallel, spaced-apart arrangement with the U-shaped rods therebetween in an interleaved arrangement. Within each set of rods, the rods are of differing lengths and are arranged so that rods with attachments to one of the material sheets adjacent to a given one of the rods differ in length from that given one of the rods. The article can be arranged so as to distribute energy of a localized blast or impact on one material sheet through the rods to laterally displaced regions of that sheet. The article can be arranged as a blast shield or as armor.
