Abstract

In this paper, an exact analysis of stress and strain for a functionally graded circular plate under transverse loading and fix boundary conditions is studied. The Young’s modules varies by power law and the loading changes by a polynomial function. These property and loading are most applicable. The influence of different functionally graded variation on the stress and displacement fields is studied through a numerical example. The exact solution shown that the graded material properties have significant effects on the mechanical behavior of the plate. The exact solution will help to prognosticate the distribution of the stress in the disk. By proper selection of the disk, the disk strength will be refine against loading. These parameters are called design parameters. Eventually, a numerical problem is solved and the impacts of design parameter are considered in order to find a proper annular disk for the specific loading.
