On the basis of a simple specific cost function for perforated, elastic plates with a microstructure of first- and second-order rib systems we derive optimal designs for axially symmetric plates with simply supported, clamped or loaded edges. The results are obtained by variational analysis and the conclusion of the analysis is that for the class of plates considered a first/second-order microstructure does not result in an improved economy as compared to the first-order microstructure.
