Thin wall pressure vessel assumption
WebNov 30, 2013 · The assumption that the principal stresses in a thin-walled circular cylinder under internal and/or external pressure are uniformly distributed through the wall thickness is a rough approximation, and the larger the thickness is by comparison with the diameter, the rougher this approximation will be.
