N2 - A methodology for the buckling analysis of composite cylindrical sandwich panels with cell breakings is proposed, based on finite element modeling and analysis using the commercial software ANSYS. The core of the thin-walled structure is a honeycomb made from polylactide (PLA) material and manufactured by fused deposition modeling (FDM) additive technology, and the inner and outer layers of the sandwich panels are made from carbon fiber-reinforced materials with brittle properties. The elasto-plastic properties of the honeycomb structure are obtained experimentally and taken into account. The novelty of the present article is the following. The influence of cell breakings on buckling of sandwich panels is analyzed. The longitudinal pressures of global buckling and global buckling modes of defected sandwich panels are analyzed numerically. Moreover, the local buckling of defected sandwich panels under the action of radial pressure is analyzed numerically too. The buckling pressures of the thin-walled structures with elasto-plastic honeycombs are analyzed computationally. Eight types of cell breakings with different cell breaking locations are considered.
