Abstract

The stress analysis of pressurized and rotating isotropic discs is a classi-cal problem which can be found in literature. In a recent paper, Kookson and Sathianathan indicated that the effect of anistropy, on the stress distribu-tion within a rotating disc, is considerable. In our proposed work, the eff-ect of pressure on stationary and steady rotating discSis studied. The stress distribution in stationary discs, under inner and outer pressures, is analyzed for different values of anisotropic constant X= A7E71 where Ee and Er are the material elastic moduli in tangential and radial directions respectively. The effect of variable parameters, radius ratio, anisotropic constant X , pressure difference, is determined for the case of orthotropic steady rotating annular discs. Our results indicate that the effect of anisotropy, on the stress distribution within a disc, is considerable.
