The hoop stress is exactly 2x the axial stress!

A tank or pipe carrying a fluid or gas under a pressure is subjected to tensile forces, which resist bursting, developed across longitudinal and transverse sections.

Wall Thickness Barlow's formula can be useful to calculate required pipe wall thickness if working pressure, yield strength and outside diameter of pipe is known.

The analysis of a thin-walled internally-pressurised cylindrical vessel is similar to that of the spherical vessel. The main difference is that the cylinder has three different principal stress …

The hoop stress equation for thin shells is also approximately valid for spherical vessels, including plant cells and bacteria in which the internal turgor pressure may reach several atmospheres.

Cylindrical pressure vessels are an axisymmetric problem, there is no shear stress on an element parallel to the axis of the cylinder. Therefore, the only normal stresses are in the directions of …

If there exist an external pressure po and an internal pressure pi, the formula may be expressed as: It can be observed that the tangential stress is twice that of the longitudinal stress. σt = 2 σL

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.

We look at more complicated structural configurations: thin wall pressure vessels, which despite their apparently higher complexity can be treated directly by statics if both geometry and …

Jul 8, 2005 · As a first approximation for burst pressure, you could use the standard hoop stress formula for a thin-walled cylinder; hoop stress = (pressure * outer radius)/wall thickness
