Abstract :
This thesis deals with the problem of the optimal design of lightweight thin-walled composite structures through the development of multi-scale procedures and numerical tools for their effective and efficient design. Two types of structures are considered: large-scale constant-stiffness composite structures, typical of the aeronautical field, and variable-stiffness composite structural components, characterised by a point wise variation of the macroscopic mechanical properties over the laminate surface. Concerning the formers, their preliminary design involves requirements related to responses at different scales of the structure and a huge number of design variables. To perform this operation the Global-Local Multi-Scale Two-Level Optimisation Strategy (GL-MS2LOS) has been developed, which combines the accuracy in responses evaluation and the proper handling of the scale transition of Global-Local approaches, with the efficient definition of the design variables of the MS2LOS. Regarding variable-stiffness composites, to foster their optimal design, on the one hand, the MS2LOS has been enhanced by the formulation of requirements on mass, strength, buckling and manufacturability, and, on the other hand, dedicated numerical tools have been developed. The application of the developed procedures to the structural design of the PrandtlPlane aircraft, presented in the H2020 project PARSIFAL, and experimental activities on optimised structural components complete the thesis work.
