Objective While dealing with design of composite structures, the number of design variables is so high that the feeling of engineers is rarely sufficient to optimise the design. In this project, sizing, shape and topological optimisation techniques are applied to several types of composites in order to reach a highly efficient use of materials in structures. Starting from present design methodologies and dealing with technological constraints coming from manufacturing processes, the aim is to develop new design methodologies allowing to enhance the quality of products and decrease the time to market new products. In order to achieve the goals, customised design systems will be build and tested in the context of SME's and big companies. New parametric modellers will be build and integrated within the customised environment. A very important feature is that the whole problem here will be treated at the geometrical level (not at the finite element one). That must guarantee, user friendliness of the proposed software tools. New design and optimisation algorithms will also be integrated. The general architecture will be the BOSS QUATTRO system, developed thanks to an other B/E project (OPTIM). The result will then be a toolbox available for further customisation in other applications. Metallic composite panels are considered here as well as classical multi layered composites. Different ways to formulate the design problem are studied and compared: sizing of plies, shape optimisation of laminates on the shell, topology of laminates etc. The problems of uncertainty and sensitivity to manufacturing defects will also be studied using rigorous methods. As part of the customisation task, the best formulations will be selected with respect to targeted design problems. Experimental testing will allow to check the accuracy of the obtained solutions.
