Analytical Homogenization for Honeycomb Sandwich Plates with Skin and Height Effects

Abstract

International audienceNumerical modeling of honeycomb sandwich plates is too tedious and time consuming. The analytical homogenization enables to obtain an equivalent homogeneous solid and its elastic stiffness. In this paper, the skin effect is considered for the in-plane shear and torsion problems, in which the two skins are relatively rigid. Homogenization models using trigonometric function series and energy method is proposed to study the influence of the honeycomb height on these moduli. The comparison between our H-model and Abaqus 3D modeling has shown very good agreement
