Description

<p>Mechanical property of polycrystalline materials such as metals is influenced by the layout and orientation of crystal grains. In addition, the influence of grain boundary energy from the difference in crystal orientation between neighboring grains is non-negligible in designing polycrystalline materials. From this background, we propose an optimal material design method focusing on the grain boundary energy caused by the difference of crystal orientation in addition to the layout and orientation of crystal grains. The proposed method is achieved by combining of the multi-phase field method with the KWC model and a decoupling multi-scale analysis method based on the homogenization.</p>
