In the previous report, we presented an optimization algorithm of two-dimensional structure subjected to a plastic deformation, where an admissible domain is assumed to be composed of microstructures with regular triangular cavities and the local cavitation size and rotation angle of the microstructure are determined so as to minimize the work done by the applied load. In this paper, several numerical examples are presented to demonstrate the validity of the algorithm. It is shown that the obtained material distribution is different from that obtained by the elastic analysis especially when a plastic hinge takes place by bending. Optimization analysis using microstructures with square cavities is also conducted to examine the effect of the shape of the microstructure, where the ultimate obtained strength increases slightly while material distribution remains essentially the same.
