Application Of Fourier Spetral Method In Homogenization Computation Of Small Periodic Complex Materials

In this paper,we use the Fourier spectral method to solve the homogenization ofperiodic composite materials.Different from the traditional finite element method,this method applies two dimensional orthogonal trigonometric function as the basicfunction.The resulting numerical solution is not only enough smooth,but also hashigh precison.The numerical examples verify the efficenty of this mehod. It is a verysignificant exploration to solve the problems about the periodic composite materialusing Fourier spectral method.
