Optimization of Laminated Composite Structures… 97
The problem in Figure 8.21 is solved with this parameterization. It includes 3750 design
variables. The optimal topology and orientations obtained for an half of the structure are
given in Figure 8.22. A comparison of the convergence speed for several approximations is
provided in Figure 8.23.
