Web10 Mar 2024 · thick wall pressure vessels is determined by the ratio between the mean radius of the vessel and the thickness of the wall. If this ratio is greater than 10, the vessel is considered a thin wall pressure vessel. If the ratio is less than 10, the vessel is considered a thick wall pressure vessel. What is thick wall cylinder? If pi= 0, Equations (8-35) and (8-36) reduce to and In this case, both the tangential and radial stresses are always compressive, with the former always the larger of the two. The maximum compressive stress occurs at the inner surface of the cylinder where the radial stress is equal to zero.
