A method of calculating the creep deflections and predicting the creep collapse of a thin-walled circular cylindrical shell, subject to uniform external radial pressure and arbitrary temperature gradients, is shown. This method may also be applied to investigate the behavior of a shell subject to time-dependent temperature gradients and deformations due to other inelastic causes. The set of simultaneous differential equations of equilibrium in terms of creep, thermal, and other inelastic strains is presented. Applications of this method to long cylindrical shells are illustrated by two numerical examples.

Experiments were carried out with 22 thin-walled circular cylindrical shells provided with localized inaccuracies representing weld flaws. It was found that along a girth weld a misalignment of the midsurfaces of the curved sheets of which the shell is welded together causes little reduction in the bursting pressure of the shell even if the misalignment amounts to three or four times the wall thickness.
