Optimality of resulting stresses in elements is determined by Hill yield criteria during each iteration, and a new optimized shell section is determined. For multiple load conditions, each element of an optimum shell reaches its allowable stress due to one or more loading conditions. </style></abstract><work-type><style face="normal" font="default" size="100%">23.
