Post-buckling load-deflection behavior of a perfect and an imperfect shell under a destabilizing load

Load-deflection curves showing limit and bifurcation points of a perfect and an imperfect shell under a destabilizing load.

Predictions of this type are computed for imperfections of very small amplitude from asymptotic analyses such as those by Koiter (1945) and by Hutchinson, Budiansky and colleagues in the 1960s and 1970s.
