Symmetric linear general buckling (“symsymgenbuck”) from BIGBOSOR4 of the linearly optimized specific case called “mich8”

Fig. 3a Symmetric linear general buckling (“symsymgenbuck”) from BIGBOSOR4 of the linearly optimized specific case called “mich8”. The length of circumferentially corrugated shell displayed here (300 inches) is six times that included in the previous figure. This 300-inch-long shell is one of the three BIGBOSOR4 models (“symsymgenbuck”, “symantigenbuck” and “antiantigenbuck”) used during optimization cycles for the prediction of general buckling. The discretized model of axial length, WIDTH/2 = 50 inches, shown in the previous figure, is first reflected to produce a portion of shell of axial length, WIDTH = 100 inches, then repeated three times to generated the BIGBOSOR4 model used for general buckling.
