We have developed a theoretical model for predicting the in-plane mechanical properties of honeycombs based on the large deflection of the inclined and vertical members of the honeycomb cells. We have used the large deflection approach for a segment including honeycomb cells. Then we derive expressions for Elastic modulus and Poissons ratios in two orthogonal directions, and the shear modulus of honeycombs. Elastic modulus, Poissons ratios and the shear modulus of honeycombs are expressed using incomplete elliptic integrals. The results show that these mechanical properties are no longer constant at large deflections but vary significantly with the strain
