Finite Element Analysis of Two Dimensional Functionally Graded Thick Rotating Disks

Abstract

The present study deals with the stress and deformation analysis of thick rotating disks made up of two dimensional functionally graded materials (FGMs) by finite element method. Material properties are distributed according to power law distribution and the disks are subjected to clamped-free boundary condition. Material modeling and finite element modeling for the disk is presented and the resulting deformation and stresses are evaluated. The effect of grading index on the deformation and stresses is investigated and presented. The results obtained show that there is a significant reduction of stresses in two dimensional FGM disks as compared to homogeneous and one dimensional FGM disks.
