Abstract :
The present study deals with the elastic analysis of concave thickness rotating disks
made of functionally graded materials (FGMs).The analysis is carried out using
element based gradation of material properties in radial direction over the discretized
domain. The resulting deformation and stresses are evaluated for free-free boundary
condition and 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 FGM disks as compared to homogeneous disks and the disks
modeled by power law FGM have better strength.
