چکیده
|
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 freefree 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.
