利用均匀化方法和基于数字图像的几何建模技术，提出了一种微结构设计方法。渐近均匀化方法的局部化能力使得能够评估微观结构中的微观变形，即，代表性体积元（RVE）。这一独特的特点使我们能够使用微观变量的功能形式的约束和目标函数。在估算微机械响应时，基于图像像素信息的系统建模方法及其处理，使得单胞几何结构的构建变得容易，均匀化结果也更加准确。因此，当在评估微观和宏观变量时考虑特定的微观结构几何形状时，可以根据我们的目标确定最佳的微观结构配置
A microstructural design method is developed by utilizing the homogenization method and digital image-based (DIB) geometric modeling technique. The localization capability of the asymptotic homogenization method enables the evaluation of the microscopic deformation in the microstructure, i.e., representative volume element (RVE). This distinctive feature allows us to use the 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
