Finite element structural shape and thickness optimization of axisymmetric shells
Abstract
The structural shape and thickness optimization of axisymmetric shell structures loaded symmetrically is investigated. In the finite element stress analysis utilization is made of newly developed linear, cubic, and quadratic, variable thickness, C(O) elements based on axisymmetric Mindlin-Reissner shell theory. An integrated approach is employed to carry out the whole shape optimization process in a fully automatic manner.
