The outer diameter is D and the wall thickness is t. The term ‘thin-wall’ may be taken to mean that D/t > 10. D t Fluid at pressure P. L P
7.3 The Thin-walled Pressure Vessel Theory
homepages.engineering.auckland.ac.nzc Circumferential stress in a thin-walled cylindrical pressure vessel (7.3.12) Figure 7.3.10: free body diagram of a cylindrical pressure vessel As with the sphere, the radial stress varies from p at the inner surface to zero at the outer surface, but again is small compared with the other two stresses, and so is taken to be r 0.

Most vessels also have closed ends - this results in an axial stress component. Principal stresses at radius r : And, if the ends are closed, 2 2 2 σ1 =σθ=−K +C/r: σ=σr =−K +C/r σ3 =σaxial =−K ...
Composite Overwrapped Pressure Vessels (COPV)
ntrs.nasa.gov3) Quantitative nondestructive testing methods used for flaw screening of thick-walled metallic structure are generally not applicable to COPV designs. Pressure vessels have historically been classified as failing due to either burst or leak-before-burst (LBB). These designations have been misleading in the past, suggesting that a vessel that is
