Effect of Thermal Gradient on Steady State Creep in a Rotating Disc of Variable Thickness

The steady state creep in a rotating FGM disc having linearly varying thickness has been analyzed in the presence of linear thermal gradient. The disc is made of composite containing silicon carbide particles (SiCp) in a matrix of pure aluminium. The content of SiCp in the disc decreases non-linearly from the inner to the outer radius. The distributions of stresses and strain rates, resulting due to disc rotation, have been estimated by imposing...
