Thermo Creep Transition in Non-homogeneous Thick-walled Rotating Cylinders

Creep stresses have been derived using transition theory⁷. The results for the combined effects of angular speed and temperature are calculated and depicted graphically. It has been observed that a cylinder made of less compressible material at the internal surface and highly compressible at the outer surface is on the safer side of the design for different values of N, Ω² and temperature as compared to highly compressible material at the internal surface and less compressible at the outer surface.
