ESO for Shape Optimization and the Reduction of Stress Concentrations

Ever since the fonnulation of the general rules and fonnulae of structural mechanics, the focus of most analyses has been to find the maximum stress present in a given structure. This maximum provided the basis of a design limit despite the obvious fact that, often, the bulk of the surface of the structure was at a much lower stress. This chapter demonstrates how the ESO technique can be used to provide structural shapes where the boundary is evolved on the basis of making the, as yet unknown, surface fonn as evenly stressed as possible.
