Abstract
An energy absorber is disclosed herein. The energy absorber includes a structure defining a hollow interior portion. The energy absorber also includes a working volume defined in at least a portion of the hollow interior portion. The energy absorber further includes shape memory alloy (SMA) particles positioned within the working volume. The SMA particles have an Austenite finish temperature (A) that is lower than a temperature encountered in an application in which the energy absorber is used so that the SMA particles exhibit stress-induced superelasticity.
