Cylinder stress (axial stress)

Description

A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure.
When a cylindrical vessel has closed ends the internal pressure acts on them to develop a force along the axis of the cylinder. This is known as the axial stress and is usually less than the hoop stress.
