This is Fig. 5.9 from the paper, "Buckling of shells - Pitfall for designers" by David Bushnell, AIAA Journal, Vol. 19, No. 9, September 1981.
Shown here is a ring-stiffened cylindrical shell and prediction of axisymmetric pre-buckling deformation that develops when the welding process is simulated by local cool-down of material in the neighborhood of the welds.
(a) cylindrical shell with internal rings
(b) pre-buckling deformation predicted by BOSOR5 when internal rings are welded to the shell skin
(c) pre-buckling deformation predicted by BOSOR5 when external rings are welded to the shell skin
