Multifunctional cellular metals (or other materials) for structural applications that are capable of recovering their original (undeformed) shape and thickness after impact or crushing (i.e., self-healing). Alternatively, they may normally be stored or used in their compressed (i.e., crushed) state and deployed when needed to act as energy absorbing structure or packaging (i.e., deployable energy absorber). Additionally, the multifunctional structures may act as an actuator, capable of providing localized or distributed force and displacement, and rela...
We claim: 1. A multifunctional member adapted for structural deformation and reformation, the multifunctional member comprising: at least one active core member, said active core member adapted to deform if exposed to an external force, and reform from a deformed state if exposed to a stimulant; at least one upper member disposed on said core member, said upper member including a plurality of upper protrusions, said protrusions generally protruding in the direction of said active core member; and at least one lower member disposed on said core member op...
