Abstract
Elastic stability of clamped shallow spherical shells subjected to a small finite-area load at the apex is studied experimentally. Upper and lower critical buckling loads and prebuckled and postbuckled deflections are found for λ between 10 and 17. Buckling modes have been observed and defined. Nonaxisymmetric deformations are noted. Shells for λ less than 8 1/2 exhibit plastic behavior and do not buckle.
