Comparison of predictions from BIGBOSOR4 and STAGS for linearly and nonlinearly optimized “mich8” configurations

The circumferentially corrugated shell of revolution is optimized subject to the following “behavioral” constraints:
Local buckling that is symmetric about the symmetry plane at X = WIDTH/2
General buckling that is symmetric about the symmetry plane at X = WIDTH/2.
General buckling that is anti-symmetric about the symmetry plane at X = WIDTH/2.
Maximum allowable stress
