摘要: Abstract A low-density nanocrystalline material was created by electroforming Ni around a rapid prototyped acrylic photopolymer micro-truss. This new hybrid combines the structural efficiency of micro-truss architectures with ultra-high strength that can be achieved grain size reduction to nanometer scale. range strut thicknesses were electrodeposited and tested in uniaxial compression. Strut failure occurred inelastic buckling core (compression) members tensile fracture face-sheet (tension) members. Experimental knockdown factors determined from idealized compressive modulus peak models used map optimal geometry terms deposited initial cross-section.
