The Axial Stress on a Cylinder calculator compute the axial stress (σa) on the outer wall end caps of a closed cylindrical pressure vessel.1 This equation assumes the inside pressure Po = 0.
INSTRUCTIONS: Choose units and enter the following:
Axial Stress on a Cylinder (σa): The calculator returns the stress in newtons per square centimeter. However, this can be automatically converted to compatible units via the pull-down menu.
The formula for the Axial Stress on a Cylinder is:
σa = P • (ri²) / (ro² - ri²)
