A number of advanced engineering systems require structures that are stiff and strong, while being capable of efficiently damping vibrations. These conflicting requirements are typically addressed by connecting two components, one providing stiffness and strength and the other offering an energy loss mechanism. Combining these opposing functions in a single architected material (possibly hybrid) could result in significant weight savings. This research explores the design space of solid elastomeric truss lattice materials coated with metallic films, and aims at identifying the lattice architecture that optimizes the combination of stiffness, strength and vibration damping.
