WebTo recap, the condition for a thin walled vessel can be written as follows. From there, you can substitute in either a or b for the value of r. Since the entire point of the approximation is that the wall is thin, the model is … WebWhile not the same, these can typically optimize the available area compared to elliptical vessels (for a given dimension A and B). As such, these are almost always the preferred design choice compared to elliptical, and more commercially available. The equations, while handling a membrane stress discontinuity, are easier.

Webσ= Note: The above formulas are good for thin-walled pressure vessels. Generally, a pressure vessel is considered to be "thin-walled" if its radius ris larger than 5 times its wall thickness t(r> 5t). When a pressure vessel is subjected to external pressure, the above formulas are still valid. WebAug 13, 2024 · As discussed previously, the equations used for design of thin-walled vessels are inadequate for design or prediction of failure of thick-walled vessels where Rin/t < 10. There are many types of vessels in the thick-walled vessel category as outlined in the following, but for purposes of discussion here only the monobloc type will be discussed.
