| Research Abstract |
Control method of a new high energy absorbing ultra light porous metal called ‘Kushidango-shape MHS structure’was examined. Kushidango-shape MHS is a tubular component in the shape of a string of hollow spheres. Consolidation method thatthe components are strongly brazed by tin solder at low temperature without heat affect was proposed. The structures in which arrangements of the components ,that is, apparent density and internal deformation behavior were changed were consolidated and theirmechanical properties were estimated by compression and bending tests. By these results, the performance can be controlled. To estimate the performance virtually, FEM simulation models of compression and bending were also established.
