摘要

The effective in-plane shear moduli of different types of honeycomb cores with thick walls are studied using analytical and numerical approaches. Analytical equations derived in this paper a proposed jointed rectangle into consideration. The analytical results under plane stress and plane stain conditions are also obtained. The effective in-plane shear moduli are studied as a function of t/l because of the different methods of describing the geometrical shapes of honeycomb cores. Then honeycomb core specimens with different t/l are prepared based on 3D printing technology for shear experiment. The results are quantitatively compared with the experimental results in this paper. It indicates that the model in this paper can predict the effective in-plane shear moduli of honeycomb cores with thick walls more accurately.
