Stress and Deformation Analysis of Variable Thickness Clamped Rotating Disk of Functionally Graded Orthotropic Material

The present study deals with the linear elastic stress analysis of rotating disks made of functionally graded polar orthotropic material whose mechanical properties vary in radial direction. The analysis is carried out using element based gradation of material properties over the discretized domain....

Description
Summary:The present study deals with the linear elastic stress analysis of rotating disks made of functionally graded polar orthotropic material whose mechanical properties vary in radial direction. The analysis is carried out using element based gradation of material properties over the discretized domain. Stress and deformation distribution for four types of thickness profiles namely uniform, linear profile, parabolic concave and parabolic convex are investigated and effects of the grading parameter and other parameters, governing the orthotropy of the material are studied for clamped-free boundary condition. The results obtained are in good agreement with established results and it can be seen that there is a significant reduction of stresses in variable thickness disks as compared to uniform disks.
