Effect of Aluminum Honeycomb Cell Geometrical Parameters on Efficiency of Material

Abstract:

The micromechanical model for predicting macroscopic effective elastic coefficients of aluminum honeycomb cores is established based on homogenization theory combined with FEM method. The effects of aluminum honeycomb cell geometrical parameters on the efficiency of materials are investigated based on the concept of material efficiency. By using MATLAB language, the material efficiencies of irregular orthotropic hexagonal aluminum honeycomb cores with various height-to-length ratio, thickness-to-length ratio and cell wall angle are simulated. The effects of cell geometrical parameters on the efficiency of material are obtained. The light-weight design for aluminum honeycomb core is analyzed in further. The results have guiding signification for the optimization design and engineering application of aluminum honeycomb core materials.
