Comparison of test and BOSOR5 theory for buckling of externally pressurized torispherical Specimens A3 - A6

This is Fig. 5 from the 1974 Galletly paper. Displayed here are the predicted bifurcation buckling mode shapes for Galletly's specimens A3 – A6. Pcr is the buckling pressure and n is the number of circumferential waves in the critcal buckling mode. (from International Journal of Solids and Structures, Vol. 10, pp. 1287-1305, 1974)
