This article deals with the study of stress distribution in a rotating cylinder made of orthotropic material by using Seth’s transition theory. The generalised strain measure is used for finding the governing equation. This model is based on stress-strain relation and on the equilibrium equation. The analytical solution is presented for the rotating cylinder made of orthotropic and isotropic material. The behaviour of stress distribution and angular speed are investigated. From the obtained results, it is noticed that isotropic material cylinder requires higher value of angular speed to yield at the inner surface in comparison to orthotropic material. The hoop stress is maximum at the inner surface for the cylinder made of isotropic/orthotropic material. Results are discussed numerically and graphically.
