Wire Formed Cellular Metals

Abstract

The authors have noted that wires could be the best candidate material to create truss PCMs, because they can easily obtain high strength as in piano wires, are simple to be fabricated, and can be controlled for good quality. Seven new ideas to fabricate truss PCMs using wires, namely, straight bulk octet, bulk woven Kagome, circular spring Kagome, hexagonal spring Kagome, dual wired octet, and dual wired Kagomes are presented. The assembly process, the geometry, features and benefit of each idea are described. Also, the analytic solutions of the stiffness or strength, and the constraints for selecting proper materials are discussed.
