%X With bending, shear and tension deformations being considered in the thin-walled beams within aluminum honeycomb cores under in-plane loadings, the analytical formulas for the in-plane elastic moduli of the aluminum honeycomb cores are derived based on Timoshenko beam theory. The finite element simulation methods for calculating these moduli for a representative unit cell are proposed based on shell elements. The calculations on the elastic moduli of two kinds of aluminum honeycomb cores are carried out, respectively, by using the theoretical and finite element methods. The agreement between the calculated results and the experimental data has verified the theoretical formulas and finite element simulation method. Finally, the effects of aluminum honeycomb cores' configuration parameters on their material efficiency are analyzed.
