Abstract

This paper is concerned with the choice of objectives or multiobjectives for the optimal shape design of axisymmetrical structures which are loaded symmetrically or non-symmetrically. The analysis of the structure is performed using the finite element method and the displacements are developed in Fourier series to take into account non axisymmetrical loadings: The following topics which have been presented in detail in earlier papers are briefly summarized — definition of the shape and selection of the design variables — analysis of the structure — sensitivity analysis and optimization method.In this paper attention is focused on the following topics: — choice of the objective functions — multicriterion optimization by combining different objective functions — multicriterion optimization by combining different terms of Fourier series — results and applications.
