ABSTRACT: Analogy between the post-buckling equilibrium form of complete spherical shells with the mandrel inside and the form of living spherical honeycomb structures is investigated. The primary aim of this paper is to describe the typical topological-geometrical properties of the multi-dimple buckling pattern of a complete spherical shell on the basis of this analogy. It was found that, although the sphere itself is the most symmetrical form, the buckling pattern on it (consisting of pentagons, hexagons and heptagons) is asymmetric.
