This is Fig. 25 from the 2010 GENOPT paper. This slide shows a STAGS sub-domain model of the optimized internally ring and stringer stiffened axially compressed cylindrical shell with a weld land. Only one ring bay and one half of a T-stiffened weld land are included in this 60-degree STAGS model.
Symmetry conditions are imposed along the two longitudinal edges. This figure shows the critical local buckling mode shape. Compare with the buckling mode displayed in the previous slide.
STAGS is often used to evaluate optimum designs previously obtained by GENOPT/BIGBOSOR4.
