It has been observed that thermal effects increase the value of angular speed required to yield at the internal surface for incompressible/compressible materials. Radial stresses have a maximum value at the internal surface of the rotating disc made of incompressible materials as compared to compressible materials. With the introduction of thermal effects, radial as well as circumferential stresses must be decreased in the absence of mechanical load but when mechanical load is applied, radial as well as circumferential stresses must be increased at the internal surface of a rotating disc with a shaft. A rotating disc is likely to fracture at the bore of the radius.

Key words: load, stress, thermal stress, stress analysis, disc, rotating disc, yielding, elasticity and plasticity.
