In this paper, the equivalent torsion rigidity for honeycomb canape is analyzed theoretically. Honeycomb canape is a honeycomb to which a face sheet is attached to the one side. We applied the rule of mixture to honeycomb canape which is composed by triangle, rectangle and hexagon cells. The theoretical analysis for triangle and rectangle honeycomb canape based on the rule of mixture is in good agreement with the results of FEM. However, there is an error factor to apply the rule of mixture to hexagon honeycomb canape. The error factor is that the rotational deformation of hexagon honeycomb core does not coincide with the face sheet. Therefore, it is necessary that the strain energy caused by the difference of the rotational deformation to calculate equivalent torsion rigidity of hexagon honeycomb canape. Then, a method to calculate equivalent torsion rigidity based on the compatibility condition of core and face sheet is proposed, and its validity is verified by using numerical results of FEM.
