| Abstract: | Based on the Ref.(1,2), a finite element method for the nohomogeneous elastic material analysing is proposed in this paper. The elastic coefficients can be numerically calculated with this method and the corresponding computational program for any nonhomogeneous isotropic elastic material. |
