SHAPE OPTIMIZATION OF AXISYMMETRICAL STRUCTURES WITH ADAPTIVE FINITE-ELEMENT PROCEDURES

A robust and versatile algorithm for shape optimization with adaptive finite element procedures is developed for the design of axisymmetric structures. The algorithm is based on the use of boundary parameteriza tion with cubic splines for describing shape changes and takes advanta ge of the utilities available in an advancing front type mesh generato r. Six-noded triangular elements are adopted. Shape optimization examp les involving solid axisymmetric structures are presented to illustrat e the various features of the integrated approach.
