Abstract

Creep behavior of a rotating disc made of isotropic functionally graded material (FGM) has been investigated. The disc under investigation is made of a composite containing silicon carbide particles in a matrix of pure aluminum. The creep behavior has been described by Sherby’s law. The disc is considered as having a thermal gradient in the radial direction. The present analysis indicates that for the assumed linear particle distribution, the steady-state strain rates are significantly lower compared to that in an isotropic disc with uniform particle distribution. It is also found that the strain rates in composite discs operating under thermal gradient are reduced as compared to similar discs under a uniform average temperature.
