面外曲げを受ける鋼板サンドイッチパネルの弾性座屈耐力

抄録

 In a sandwich structure having a thin plate, it is of critical importance to understand the buckling behavior of the surface material. The purpose of this study is to seek to clarify the elastic buckling strength of steel sandwich panels under out-of-plane bending and evaluate it by simple formula. For this purpose, by extending the previous theory for in-plane compression, the authors propose a theory for the elastic buckling strength of steel sandwich panels under out-of-plane bending. Furthermore, the authors analyze effect of material properties of core and skin, shape of steel sandwich panel on elastic buckling strength under out-of-plate bending, and propose simple formula for evaluating it.
