Numerical technique for the 3D microarchitecture design of elastic composites inspired by crystal symmetries

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 usin...
