OS1336-395 エッグボックスパネルの衝撃吸収特性評価

抄録

In this paper, effect of basement on the compressive response of the egg-box panels, which is consisted by a conical frusta and the base is studied by a using finite element method (FEM). It is found that there are various deformation modes by changing the length of the base and the cone angle. In addition, changing the strain-hardening coefficient and the thickness of the egg-box have a large effect on the axial crushing characteristic. Based on these facts, it is possible to propose an egg-box panel in which the peak load and load fluctuation are controlled.
