Neue zelluläre Metalle mit erhöhter Energieabsorption. Hybridwerkstoffe aus Kagome-Drahtstrukturen (WBK) und Metallhohlkugeln (MHS)
Abstract
Two types of new cellular metals are fabricated by assembling layer by layer helically-formed wires with MHS (metal hollow sphere) arrays. In the finished configuration, the MHSs are located in small tetrahedrons or octahedrons of the inner space of a WBK (wire-woven bulk Kagome) structure. Compression tests reveal excellent energy absorption, which is attributed to combination of suppression of strut buckling in the WBK and moving plastic hinge occurring in the MHSs. The WBK-MHS hybrids outperform competitors in deformation energy absorption.
