—Thin spherical shells usually fail due to buckling.
An empirical equation to predict their buckling load is derived
based on the theorem of work done and energy released in the
inversion of a section of a shell and nonlinear finite element (FE)
modeling done using ABAQUS to determine their post-buckling
behavior. It is observed that the initial buckling is sensitive to
initial geometrical imperfections but the post-buckling load is
little influenced. Therefore, the post-buckling load is used to
predict a more realistic load as compared to classical buckling
