ABSTRACT
Seth’s transition theory is applied to the problems of characterization of material in a rotating disc subjected to a thermal gradient. It has been observed that the disc made of saturated clay, copper, and cast iron materials yields at the outer surface at a higher angular speed as compared to the disc made of rubber material at a steady-state temperature, whereas disc made of clay, copper, cast iron as well as rubber material yields at a lesser angular speed as compared to a rotating disc at the room temperature. With the introduction of temperature, the radial as well as hoop stresses, decrease with the increased value of the temperature at the elastic–plastic stage, but the reverse result obtained for a fully plastic case.
