Abstract
In at least some aspects, an auxetic structure includes a first sheet defining therein a plurality of a plurality of structural elements projecting from the first sheet, the plurality of structural elements being arranged to provide a negative Poisson's ratio, and a second sheet disposed adjacent the first sheet to define a first internal cavity between the first sheet and the second sheet. In yet other aspects, one or more additional sheets may be advantageously provided to provide a multi-layered structure having auxetic properties.
