Abstract
The present study proposes topology optimization of a microstructure for composites considering the macroscopic structural response applying a decoupling multiscale analysis based on a homogenization approach. The stiffness of the macrostructure is maximized with a prescribed material volume of constituents under linear elastic regime. A gradient-based optimization strategy is applied and a semi-analytical sensitivity approach is introduced. It was verified from a series of numerical examples that the proposed method has great possibility for microscopic advanced material designs.
