Description
図7は、構造体10を並列して配置した状態を示す模式図である。ここで、位置が隣接する構造体10を、説明の便宜上、構造体10a、構造体10bとする。構造体10aにおいて、横方向の潰れ部分11を潰れ部分11aA、縦方向の潰れ部分を潰れ部分11aB、潰れ部分11aAと潰れ部分11aBの間の中空四面体構造12を中空四面体構造12aとする。構造体10bにおいて、横方向の潰れ部分を潰れ部分11bA、縦方向の潰れ部分を潰れ部分11bB、潰れ部分11bAと潰れ部分11bBの間の中空四面体構造12を中空四面体構造12bとする。図7に示すように、位置が隣接する構造体10aと構造体10bは対称になるように90°位相を変えて配置されている。
本試験では、異なる仕様の中空管1より成形した3つの構造体10について、それぞれ、プラトー応力[MPa]及び単位質量あたりの吸収エネルギー[kJ/kg]を評価した。ここで、プラトー応力とは、圧縮応力-圧縮ひずみ曲線において,プラトー領域内の応力で,通常20~30%の圧縮ひずみでの圧縮応力の平均値である。
