Design of cylindrical honeycomb cores – Geometric consideration –

Lightweight and rigid honeycomb cores have a feature as deployable structures, i.e., their shapes can be changed as desired from the viewpoint of manufacturing processes. This paper presents a geometrical design method for cylindrical honeycomb cores that satisfy high rigidity and deployability, con...
