Stress in thin-walled pressure cylindrical vessels
Description
A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. Stress in a shallow-walled pressure vessel in the shape of a cylinder is related to the internal gauge pressure, the inner radius of the cylinder, the thickness of the wall and the density of the material. A vessel can be considered “shallow-walled” if the diameter is at least 10 times (sometimes cited as 20 times) greater than the wall depth.
