摘要：

In this study, in order to calculate the bending rigidity of a honeycomb, a torsion problem of a board was analyzed by using the generalization variation principle. The analysis was checked by using the numerical analysis of FEM. In the torsion problem of a board, the boundary condition that rotation angle is zero on two edges is fulfilled. Also, the bending rigidity of honeycomb was investigated using board torsion coefficient qr, obtained from the analysis of the torsion problem of a board. It is shown that the bending rigidity of honeycomb is mostly proportional to the 3rd power of height k of the honeycomb, and in h/l>0.5, is mostly proportional to thickness t of the cell board, which constitutes the honeycomb.
