G0301-2-7 Structure Analysis on Honeycomb Panel with Dia-cut Patterned Core

Abstract

The core of the diamond cutting type was placed instead of the hexagonal core used with a usual honeycomb panel. These panels were analyzed by the finite element method when the static bend load was applied. If the area of the joint part with the surface plate is enlarged, it has been understood that the concentration of stress can be decreased, and the deflection of the panel that uses the diamond cutting type core decreases compared with the hexagon honeycomb of the same weight and the rigidity improves.
