パラメトリックモデリングを活用した面内圧縮力を受けるハニカムパネルの座屈解析

When honeycomb sandwich panels are used for bridge webs, we must consider the situation where the panel is loaded in the plane direction and supported on all edges. However, buckling load of the honeycomb sandwich panels are not clear. Therefore, we conducted a lot of the finite element analysis together with parametric modeling method. As a result, it was found that the buckling load of the honeycomb panel is large when the overall buckling mode occurs. The buckling modes are divided into four regions depending on the panel geometry. The buckling load is 50% to 80% of the buckling load of a solid medium flat plate of equal thickness.
