Abstract

Chapter 6 deals with structural shape and thickness optimization of SORs and prismatic shell structures. The basic algorithm for SSO is described first. Basically, SSO procedures involve the efficient integration of structural shape definition, automatic mesh generation, structural analysis, sensitivity analysis and mathematical programming methods. Details of the definition of the optimization problem and design sensitivity evaluation are presented. Only brief details of the optimization algorithm adopted are given because, in the present context, it is just used as a black box. Several examples of shape and thickness optimization of SORs and prismatic shells are included.
