Carrying Capacity of Elastic-Plastic Shells With Various End Conditions, Under Hydrostatic Compression

This paper considers the influence of the beam-column effect on the carrying capacity of hydrostatically loaded elastic-plastic cylindrical shells. Specific problems considered include shells with clamped ends, simply supported ends, and a combination thereof. It is shown that in all cases considered there exist two characteristic modes of failure corresponding, respectively, to long and short shells where the terms “long” and “short” are unambiguously defined. Detailed results are presented graphically along with general conclusions useful for design purposes.
