For honeycomb subjected to in-plane loading, there exist deformations in the height direction for cell walls due to effect of Poisson's ratio. Because these deformations are different for adjacent walls, the elastic modulus of honeycomb should be analyzed as a 3-dimensional problem. In this paper, the method of analysis for the equivalent elastic modulus E_1 proposed by authors in the 1st report, in which the effect of height h of the honeycomb core on the elastic modulus is taken into account, is applied to theoretical formula for calculating Young's modulus E_1 and shear modulus G_12. Then, the validity of the proposed theoretical formula for elastic moduli E_1 and G_<12> is verified comparing with the numerical results by FEM.
