摘要
The absorption energy in a closed-cell structure was enhanced by performing an increase in the aspect ratio of cell-wall thickness against the cell-edge length with the reduction of cell size. The adsorbed energy in a modified foam was estimated in comparison with that in a conventional ALPORAS with the same relative density. It was found that the plateau stress of the modified foam exhibit a remarkable increase as compared to a conventional foam.
