Abstract:

This article presents a parametric analysis for purely elastic analysis of rotating disks made of functionallygraded materials (FGMs). The solution is based on von Mises yield criterion. The material properties, except Poisson’sratio, are assumed to varying as power function across the thickness direction. To the best of authors’ knowledge, inprevious researches which onset of yield is investigated, variation of material density is ignored, while density is notconstant in FGM rotating disks. Elastic-limit angular speeds and partially elastic deformations are investigated. Theprofiles are plotted for different values of the inhomogeneity constant for the radial displacement, radial stress, andcircumferential stress, as a function of radial direction.
