This study explored the buckling of multiple intersecting spherical shells. A three-segment spherical shell was designed using the theory of deformation coordination; the design was compared with that of a volume-equivalent cylindrical shell and ring-ribbed cylindrical shell. The numerical results indicated that the buckling capacity of the three-segment spherical shell was superior to those of the other two cylindrical shells. To validate our numerical approach, three laboratory-scale shell models were fabricated. Each model was accurately measured and slowly tested in a pressure chamber; thus, the tested shells were studied numerically. The experimental collapse modes agreed well with numerical results, and the collapse load of the three-segment pressure shell was considerably higher than that of the two cylindrical shells.

The title of the article "Buckling of Multiple Intersecting Spherical Shells Under Uniform External Pressure," written by Zhang, J., Li, S., Cui, W. et al., was spelled incorrectly. The original article has been corrected.
