Analysis and optimal design of plates and shells under dynamic loads - II: Optimization
In this paper a structural sizing and shape optimization procedure is used to obtain optimum designs for plates and shells under dynamic loads. The optimum designs are obtained by using an integrated system for structural optimization of shells that is formed by a set of independent 'subsystems'. They are surface and mesh generation, finite element analysis, sensitivity analysis, and optimization algorithms. The description of the geometry and mesh generation tools, as well as the implementation and test of the structural dynamic and sensitivity analysis, were given in Part I of this paper. In this part the tools presented in Part I are used along with an optimization algorithm to perform structural shape and sizing optimization (SSO) of shell structures. The sequential quadratic programming algorithm is used to solve the optimization problem. In the present paper special attention is devoted to the problem of elimination of clusters of multiple eigenvalues in the optimal design of symmetrical shells. Several examples are considered that illustrate the potential of the developed tool.
