Abstract

In the present study, the influence of anisotropy on the creep behavior of a rotating disc made of Al-SiCw composite having varying (linearly/non linearly) thickness has been studied in the presence of thermal residual stress. The steady state creep behavior is described by Sherby’s creep law. The creep behavior has been analyzed using isotropic/anisotropic Hoffman yield criterion. The creep parameters have been evaluated using the available experimental results in the literature using regression analysis. The stress and strain rate distributions are calculated for different combinations of anisotropic constants. It is concluded that the effect of anisotropy in composite rotating disc with thermal residual stress has a significant change on strain rate, although, its effect on stresses is relatively small.
