This is Fig. 41 of the 2014 GENOPT paper.
Specific case called “fold98updown”: The optimized complex corrugated “flat” wide panel of width = 3xWIDTH is mapped onto a cylindrical surface with average radius, RCYL = 318 inches. Top frame: the undeformed profile. Bottom Frame: the critical buckling mode predicted by BIGBOSOR4. A STAGS model and the corresponding critical buckling mode predicted by STAGS are displayed in the next slide .
