- Abstract
In the article a sandwich structure with circular cells of honeycomb core is investigated in order to study the correlation between mechanical behaviour and weight for this structural model. A numerical model is built using Abaqus cae software to predict the out-ofplane elastic properties and the relative density of the honeycomb core, considering a unit cell as a Representative Volume Element (RVE) of the core. A parametric study is also performed to investigate the effects of cells' wall thickness and cells' radius on the overall mechanical behaviour of the honeycomb core. The maximum deflection and skin stresses for the entire sandwich structure are modelled using analytical equations. Then, the analytical solution is compared with Finite Element analysis. These results showed excellent agreement. The investigations showed that the honeycomb core unit cells' wall thickness and the cell's radius have a significant effect on the mechanical behaviour and the weight of the honeycomb core.
