AB - The non-homogeneity is assumed due to variation of modulus of compression. It  has seen that in the presence of temperature, a cylinder made of  non-homogeneous material k<0 (Non-homogeneity is less at internal surface  than at outer surface) require high pressure to become fully plastic as is  required for initial yielding and this pressure goes on increasing with the  increases in temperature, showing that a cylinder made of non-homogeneous  material k<0 is on the safer side of design. For homogeneous case, it has  been observed that the circumferential stress has maximum value at the  external surface of the cylinder made of incompressible material as compared  to compressible material. For Homogeneous case, with effects of temperature  reduces the stresses at the external surface of the cylinder in comparison to  pressure effects only. Strain rates are found to be maximum at the internal  surface of the cylinder made of compressible material and they decrease with  the radius. With the introduction of temperature effect, the creep rates have  higher values at the internal surface but lesser values at the external  surface as compare to a cylinder subjected to pressure only.
