摘要：The present study deals with stress analysis on functionally graded rotating annular discs subjected to temperature distributions parabolically decreasing with radius. Authors used infinitesimal deformation theory of elasticity and for graded parameters power law functions in the solution procedure. With the increasing temperature, the tangential stress component decreased at the inner surface whereas increased at the outer surface, and the radial stress component reduced gradually for all the temperature distributions. The magnitude of the tangential stress component was higher than ones of the radial stress component under the room temperatures for both discs. But, the tangential stress component decreased more at the inner surface whereas it increased at the outer surface when the temperature increased further. Finally, the radial displacement at the outer surface had higher value than that of the inner surface with the increasing temperature.
