Abstract
A numerical methodology developed for the microarchitecture design of 3D elastic two-phase periodic composites with effective isotropic properties close to the theoretical bounds is here presented and analyzed. This methodology is formulated as a topology optimization problem and is implemented using a level-set approach jointly with topological derivative. The most salient characteristic of this methodology is the imposition of preestablished crystal symmetries to the designed topologies; we in...
