This is part of Fig. 33 of the 2014 GENOPT paper.
The BIGBOSOR4 multi-WIDTH flat wide panel model shown 10 slides ago (top frame) is “bent” inextensionally into 90 degrees of a cylindrical shell with an average radius, RCYL = 318 inches. The previously optimized weight of one section of width, WIDTH=100 inches, is 97.16 lb (top frame 12 slides ago). Therefore, the weight of 90 degrees of the cylindrical shell is 5 x 97.16 = 485.8 lb. The next figure shows buckling modes of this cylindrical shell.
