Abstract

Described is a micro-lattice damping material and a method for repeatable energy absorption. The micro-lattice damping material is a cel lular material formed of a ihree-dim.ensio.aal interconnected network of hollow tubes. This material is operable to provide high damping, specifically acoustic, vibration or shock damping, by utilizing the energy absorption mechanism of hollow mbe buckling, which is rendered repeatable by the micro-lattice architecture.
