| Abstract: | In order to simplify the calculation process of hexagonal assembly homogenization,and en-hance the adaptability of homogenization method for hexagonal geometry,a simple irregular region transfor-mation method is proposed in this paper,by which these irregular regions such as assembly wrapper and water gap can be transformed into regular hexagon with the constraint condition that material mass remains con-stantly.The numerical results show that it is a very accurate and efficient method for the prediction of... |
