In this paper, the displacement and stress distribution in a rotating FGM (Functionally graded material) circular disk with a variable angular speed are studied. The modulus of elasticity and mass density of the circular disk are assumed to vary along its radius and relate to the volume fraction of the materials, while the Poisson's ratio remains to be a constant. The motion equations of the FGM rotating circular disk are simplified into boundary value problems of ordinary differential equation, which are solved by Runge-Kutta method, and the whole problem is solved by utilizing shooting method. Numerical results show that the functionally graded index, angular speeds and geometric shape all have significant effect on the mechanical behaviors of the rotating FGM circular disk. The results of this study may be useful for other investigations of a rotating FGM circular disk. [ABSTRACT FROM AUTHOR]
