Finite Element Solution for Stress and Strain in FGM Circular Disk

摘要

In this work, finite element method (FEM) is employed to study thermoelastic characteristics (radial stress, circumferential stress, radial strain and circumferential strain) of two functionally graded material (FGM) disks under two distinct cases of temperature distribution. The material properties of the disks are assumed to vary as linear function of radius. The Poisson's ratio is assumed as constant because its effect on characteristics is negligible. The first disk constructed by using two functionally graded materials Al and Al_2O_3 on the other hand second disk is constructed with help of functionally graded materials Zr and ZrO_2. Graphical results shows,significance difference between thermoelastic characteristics for two disks under two different temperature distributions.
