“…In this problem, we have considered only the principal stresses and it has been shown that [5][6][7][8] transition through τ rr − τ θθ results in creep state for the critical point Q → -1. Thus transition function R is defined as…”

“…Transition theory with the concept of generalized strain measure [5] eliminates the use of above assumptions to investigate the stresses i.e. Gupta et al [6] determined thermal creep stresses in thick isotropic spherical shell under internal pressure and concluded that shells made up of incompressible material requires high pressure to yield. Sharma et al [7] investigated thermal creep stresses and concluded that thick-walled circular cylinder under external pressure is better for the designing purpose as compared to homogeneous cylinder.…”

Creep stresses have been analyzed for pressurized thick-walled functionally graded rotating spherical shell with thermal effects. This paper aims to investigate the creep stresses in rotating functionally graded spherical shell. Transition theory using the concept of generalized measure has been used to investigate these creep stresses in rotating shell. From the numerical discussion, it has been observed that both rotation and non-homogeneity plays significant role on thermal creep stresses.

“…For finding the creep stresses and strain rates, we discuss the transition of the spherical shell at P 1   . We define the transition function R through principal stress difference (see Deepak [13][14], Thakur [15][16], Sharma [17], Verma [18][19] ) at the transition point P 1   . The transition function R is given as…”

In the present paper, we have studied the temperature and pressure dependent creep stress analysis of spherical shell. The review is critical to enhance the warm resistance of spherical shells in high-temperature conditions. The effect of different parameters was studied and it was noticed that the parameter n has a significant influence on the creep stresses and strain rates. Creep stresses and strain rates are ascertained on the premise of summed up strain measures and Seth’s transition hypothesis. This investigation is completed to demonstrate the impacts of temperature on the creep stresses and strain rates in the spherical shell. The resulting quantities are computed numerically and depicted graphically. It has been watched that the spherical shell made of an incompressible material is on more secure side of configuration when contrasted with the shell made of a compressible material.
