The Effect of Face and Side Panels of Honeycomb Core on its Equivalent In-Plane Elastic Properties

Abstract:

The effect of the face and side panels of honeycomb cores on their equivalent in-plane elastic properties is studied by the numerical simulation in this paper. The numerical results show that the deformation pattern of the honeycomb core constrained by either face panels or side panels is totally different from that of pure honeycomb materials. As a result, both the face panels and the side panels of honeycomb cores significantly increase the equivalent in-plane moduli of honeycombs. The commonly used prediction model of honeycombs cannot be used for the evaluation of the additional in-plane tensile stiffness contributed from the honeycomb core. However, the prediction model for the equivalent in-plane moduli of honeycombs with the periodic displacement condition yields much better results.
