An application of theoretical solutions about cylindrical shells with small openings

Stress concentrations about thin cylindrical shells with small openings are reconsidered from a new angle. There is a sort of special internal relation between theoretical solutions about cylindrical shells with large openings and one with small openings. Using this relation, the extent of applying the theory about small openings to engineering practice is estimated again, thus an idea of how to use this theory and a new appraisal of the application of theoretical solutions about cylindrical shells with small openings to engineering practice are given.
