The effect of short time creep on the resistance of smooth and waffle surface cylindrical casings

1. Under conditions of short time creep the bulging of smooth cylindrical casings subjected to the action of axial compression and internal pressure with a pressure parameter of p>0.5 and circumferential stress greater than 0.5 times the tensile strength of the material is asymmetrical. 2. In view of the high sensitivity of the creep process to a change intemperature, nonuniformity in the temperature distribution in the longitudinal direction leads to intense development of bulging. 3. The results of calculations using the method of additional deformations agrees satisfactorily with the experimental data.
