| Abstract | Functional gradation of materials in a component, whether metal-metal, metal-ceramic, or ceramic-ceramic, offers benefits such as high toughness and strength at elevated temperatures, which are desirable traits in rotating disks. With the advent of FGMs, isotropic material components began to be replaced. In the present study, Thermo-mechanical stress analysis on rotating disks was performed for isotropic materials (both metal and ceramic), and their results were compared with those of a linearly varying functionally graded (FG) disk. The approach utilized is the Variational principle, deriving the solution through Galerkin's error minimization method. Comparison plots of displacement, radial and tangential strains, as well as radial, tangential, and von Mises stresses, were presented to illustrate the advantages of advanced materials such as FGMs (functionally graded materials) over isotropic materials. The study reveals the benefits of functional grading of disks over those made of isotropic materials. Moreover, the analysis was performed for uniform as well as tapered disk profiles. |
