Elastic buckling of cylindrical shells with elastic cores. I: Analysis. II: Experiments. (English) Zbl 0872.73016
We analyse the elastic buckling of a thin cylindrical shell supported by an elastic core to show that this structural configuration achieves significant weight saving compared to a hollow cylinder. Biomimicking of natural cylindrical shell structures may offer the potential to increase the mechanical efficiency of engineering cylindrical shells.
