Abstract

Mathematical modeling for steady-state creep has been done for an anisotropic disc of aluminium-silicon carbide particulate composite rotating at elevated temperatures under a thermal gradient. Creep modeling and analysis has been done using Hill’s yield criterion for a disc operating under a parabolic distributed temperature and its comparison is made with the disc operating under uniform temperature throughout the radius. The results are expressed graphically in designer friendly manner for the stress and strain rate distributions under a graded temperature field. It can be seen that the parabolic temperature field has a significant effect on the creep behavior of the anisotropic disc. Thus, the temperature gradient effect should be considered while designing the anisotropic rotating disc.
