The present research deals with thermal behaviour in a rotating disc of transversely isotropic material with rigid shaft by using transition theory and generalized strain measure. It has been seen that the radial stress has a maximum at the internal surface of the disc made of transversely isotropic material. Transversely isotropic material required higher value of radial stress at the internal surface of measure n = 1/5 in comparison to the disc of isotropic material, meaning that the transversely isotropic material is more comfortable than that of isotropic material. By increasing the values of angular speed and thermal condition, the value of radial stress as well as tangential stress must be increased at the internal surface depicted graphically. With the introduction of thermal condition the creep strain rates increase at the internal surface of the disc of isotropic material.
