The purpose of this paper is to present the study of material characterization in a rotating disc subjected to thermal gradient by using Seth’s transition theory. It has been observed that a disc made of materials as: saturated clay, copper, or cast iron, yields at the outer surface at higher angular speed as compared to the disc of rubber material at steady state temperature, whereas the disc made of clay, copper, cast iron, as well as rubber material, yields at a lesser angular speed as compared to the rotating disc at room temperature. With the introduction of temperature, the radial- as well as the hoop stress, both decrease with the increased value of temperature at the elastic-plastic stage, but with the reverse result obtained for a fully plastic case.
