Abstract
A computer system generates a lattice structure effective to satisfy static loading criteria, the lattice structure including surfaces, nodes, and branches interconnecting nodes. The branches are removed and various alternative configurations are tested to identify one that meets low frequency damping requirements. An outer damping layer is selected to satisfy high frequency damping requirements and is added to the lattice structure. The lattice structure may then be fabricated using an additive manufacturing device.
