Analyses of Creep behavior in Composite Disc with Thickness Variation

Vandana Gupta

Abstract: This study focuses on analyzing the impact of thermal gradients on plastic stress patterns and creep deformation in a rotating isotropic disc with variable hyperbolic thickness subjected to thermal gradients. The findings reveal that thermal residual stresses significantly affect both stresses and strain-rates behavior in functionally graded material discs. Therefore, accounting for thermal gradients is essential for improving performance and ensuring optimal structural design.
