描述Shape and layout optimization represent some of the most useful but also most difficult classes of problems in structural design, which have been investigated in detail only during the last few years. .Shape optimization. is concerned with the optimal shape of boundaries of continua or of interfaces between two materials in composites. .Layout. .optimization. deals with the simultaneous optimization of the topology, geometry and cross-sectional sizes of structural systems. In spite of its complextiy, layout optimization is a very rewarding task, because it results in much greater savings than the optimization of cross-sectional sizes only. Because of their important role in shape and layout optimization, the book also covers in detail new .optimality . .criteria methods., which are capable of handling many thousand design variables and active design contraints. Shape and layout optimization is becoming an indispensable tool in the design of aeroplanes, space structures, cars, ships, building and civil engineering structures, power stations, chemical plants, artificial organs, sporting equipment, and all other solid systems where stresses and deformations play an important role.

COC Methods for Additional Geometrical Constraints,cannot handle such large numbers of elements, the analysis capability of these is expected to keep on increasing in the foreseeable future. The COC algorithm, therefore, represents an optimizer that . in the optimization of large structural systems.

Mixed Elements in Shape Optimal Design of Structures Based on Global Criteria,to the optimal shape design of two dimensional elastic structures, selecting the compliance as the objective function to be minimized and the initial volume as constraint. The advantages and disadvantages of the mixed elements are discussed with reference to applications.

Mathematical Programming Techniques for Shape Optimization of Skeletal Structures,imum layout to be designed. The third type of method includes those which allow for topological considerations at certain points during the design process and generally keeps the design variables in two separate groups. The paper discusses the way in which each of the mathematical programming methods has been applied to these approaches.

In optimal elastic design, however, which is to be discussed in this chapter, it is usually necessary to resort to numerical methods because the equations involved are too complicated for an analytical treatment. Moreover, whilst in optimal plastic design (Fig. 6) we had a half rea
