| Abstract: | The mathematical theory of homogenization method,which has developed since the 1970s, is used as an alternative approach to find the effective properties of the equivalent homogenized material. In this paper, multi-scale homogenization method is applied for structural optimization of perforated plates based on finite element analysis, and its theory for calculating effective elastic constant is presented. Therefore the flow chart of perforated plates structural optimization is built. Its FORTRAN programmes are linked with the ANSYS software, and the optimal design of perforated plates is achieved. The result obtained show that it can meet the demand of engineering application, and a new design method is presented for perforated plates structures. |
