Creep transition stresses of a thick isotropic spherical shell by finitesimal deformation under steady state of temperature and internal pressure

Abstract

Creep stresses for a thick isotropic spherical shell by finitesimal deformation under steady state temperature and internal pressure have been derived by using Seth?s transition theory. Results are depicted graphically. It is seen that shell made of incompressible material require higher pressure to yield as compared to shell made of compressible material. For no thermal effects, the result are same as given by Gupta, Bhardwaj, Rana and Hulsurkar [1,3] and Bhardwaj, Bailey [2,4].
