Seth's transition theory of creep, which neither requires the creep laws nor the yield criteria and the associated flow rules, has been used to derive the creep stresses in shells under uniform internal pressure when the steady state creep has been reached. It has been shown here that the creep stresses and the assumed stress‐strain rate relations are the same as those given by Bailey. It is also found that the transition points may be multiple points and may therefore be used for finding either plastic or creep stresses depending upon the transition functions. This theory can be also readily applied to the primary and tertiary states of creep.
