• Transient creep of pressurized circular cylindrical shells is analysed according to the strainhardening and the time-hardening theories on the basis of the power creep law and the Mises criterion. Total strain is assumed to consist of elastic and creep components. Equations of equilibrium are replaced by the corresponding difference equations in regard to the rate of displacement, and the solutions of the resulting simultaneous linear equations are integrated numerically with respect to time. Numerical calculations are performed for simply supported shells of 0.15 per cent carbon steel at 450℃ subjected to constant internal pressure. The difference between these two kinds of hardening theory and the effect of the length of shells are discussed.
