| Abstract(J) | 本研究ではラティスをコアとしたサンドイッチ円筒の軸圧縮時の応答について非線形有限要素法による検討を行った．サンドイッチ円筒の軸圧縮時の第一ピーク荷重は円筒全体の寸法により支配的である一方，ラティスコアは変形挙動を非軸対称変形から軸対称変形へ制御し，吸収エネルギー量を高める効果があることが確認できた． Translation |
| Abstract(E) | In this paper, the axial compressive response of lattice-cored sandwich tubes has been studied by using a nonlinear finite element method. It is found that the first peak load of the sandwich tube is mainly dominated by the overall geometry of the tube, and less dominated by the lattice core. On the contrary, the contribution of the lattice core on the compression behavior is to change the non-axisymmetric deformation mode into the axisymmetric mode, as well as to enhance the amount of absorbed energy. In addition, an estimation technique for evaluating the absorbed energy per unit mass was proposed. |
