Abstract: Finite Element Method (FEM) is a new field of analysis which has become a steadfast method, as applied to Thermal and structural analysis. By the application of Finite Element Analysis in day to day design tasks reduces cost effectively, with capabilities spreading a broad scope in industries. As academics and increase in commercial software becoming accessible, it turns into basic tool for effective analysis. FEM enables the evolution of quality products within a short design cycle with less number of field failure depending on the skill of the analyst. In this paper study of radial stress distribution between two different materials i.e., a homogeneous rotating disc compared with material of Functional grading are done and respective results are compared. The first case of gradation is by varying the poison’s ratio linearly and other is by parabolic variation. Resulting radial stress equation is derived by applying the linear variation and the related boundary conditions. Results are amply illustrated by defining coding by applying boundary conditions and then contours plotted with respective results.
