Abstract

In this paper Elastic and thermal stress analysis of FGM rotating disks are done. The disk is made up of functionally graded material, whose mechanical and physical properties vary exponentially in radial direction. Uniform as well as variable thickness (concave, linear and convex) rotating disks subjected to linear temperature field are formulated and analyzed. The disk is modeled as axisymmetric body and 8-noded quadrilateral element is used for finite element formulation. Resulting displacement and stresses induced in the disks due to centrifugal force and uneven temperature distribution are evaluated in ANSYS Mechanical APDL and compared.
