Abstract
The objective of this paper is to investigate the effect of rotation on the radial deformation and the corresponding stresses in a non-homogeneous hollow elastic cylinder rotating about its axis with a constant angular velocity under plane strain assumption. The material of the cylinder is assumed to be non-homogeneous and cylindrically orthotropic material. The results indicate that the effect of rotation and inhomogeneity are very pronounced. The results obtained are compared in the corresponding homogeneous, in the absence of rotation and isotropic case. The variation of stresses and displacement has been shown graphically.
