Creep deformation in a thick-walled spherical shell having steady state temperature

This article deals with the study of creep deformation in a thick-walled spherical shell under steady state temperature by using transition theory and generalised strain measure. Mathematical modelling is based on stress-strain relation and equilibrium equation. Analytical solutions are presented in a thick-walled spherical shell made of saturated clay, steel and rubber materials. The shell made of rubber material requires higher pressure to yield in comparison to the shell made of saturated clay/steel material without thermal effects.
