Theoretical-Calculation Method for Design on External Pressure Vessel and Application

Chen Sheng-miao

Abstract

The analytical formula for design on external pressure vessel was disclosed based on R.V.Mises critical pressure formula.The formula can be applied to design and calculate the long and short cylindrical steel shell in elastic instability.And the applications conditions of the formula were introduced,especially the ratio of shell thickness to internal diameter δ/Di and design external pressure P were investigated.The calculation results are accordance with the one based on nomography.From the examples in this paper,the availability of the analytical formula is apparent.
