Abstract
The multifunctional performance of stochastic (foamed) cellular metals is n ow well documented. This article compares such materials with the projected capabilities of materials with periodic cells, configured as cores of pane ls, tubes and shells. The implementation opportunities are as ultra-light s tructures, for compact cooling, in energy absorption and vibration control. The periodic topologies comprise either micro-truss lattices or prismatic materials. Performance benefits that can be expected upon implementing thes e periodic materials are presented and compared with competing concepts. Me thods for manufacturing these materials are discussed and some cost/perform ance trade-offs are addressed. (C) 2001 Elsevier Science Ltd. All rights re served.
