The classic equation for hoop stress created by an internal pressure on a thin wall cylindrical pressure vessel is: σ θ = P · D m / ( 2 · t ) for the Hoop Stress. Thin Wall Pressure Vessel Hoop Stress Calculator. Where: P = is the internal pressure. t = is the wall thickness. r = is the inside radius of the cylinder.
The thin-walled pressure vessel expands when it is internally pressurised. This results in three principal strains, the circumferential strain c (or tangential strain t ) in two
The thin-walled pressure vessel analysis is formulated based on the assumption that the vessels fulfil the criteria r/t ≤ 10, i.e. the vessel is sufficiently thin with respect to its radius. Here we look at the 2 most common types of vessels: Cylindrical vessels. Spherical vessels. Cylindrical vessels. Let’s look at a cylindrical vessel.
The vessels are referred to convenient orthogonal r-θ-z axes where r is the radial coordi-nate, and and z. θ are circumferential (or hoop) and axial (or longitudinal) directions for the cylindrical vessel while they are any arbitrary orthogonal tangential directions for the spherical vessel.
Both for their value in demonstrating two-dimensional effects and also for their practical use in mechanical design, we turn to a slightly more complicated structural type: the thin-walled pressure vessel. Structures such as pipes or bottles capable of holding internal pressure have been very important in the history of science and technology.
