Abstract

A numerical method is developed for shape optimization of axisymmetric structures based on choosing the sets of fictitious loads acting on a structure‘s ’control point’ as the optimizing design variable. The axisymmetric structure is decomposed by using an isoparametric parabolic-type element that has high accuracy for design sensitivity analysis. An efficient analytic method, based on a fictitious load variable, is developed for sensitivity analysis in shape optimization of the axisymmetric structure. Two optimization examples have been tested successfully.
