A microstructural design method is developed by utilizing the homogenization nethod and digital image-based(DIB)geometric modeling technique. The localization capability of the asymptotic homogenization method enables the evalutation of the microscopic deformation in the microstructure, i.e., representative volume element(RVE). This distinctive feature allows us to use microscopic variables in the functional forms of constraints and objective function. In estimating the micromechanical responses, the systematic modeling method in terms of the pixel information of images and their processing make the construction of unit cell geometry easy and the homogenization results accurate. Therefore, while the specific microstructural geometry is taken into account in evaluating the micro and macroscopic variables, the optimal microstructural configurations can be determined depending on our objectives
