Hoop Stress Calculator
Hoop stress, also known as tangential stress, is a crucial factor in the design and analysis of pressure vessels and piping. It’s the stress acting perpendicular to the longitudinal axis of a cylindrical shell. Calculating hoop stress is vital to ensure the safety and integrity of these structures under various pressure conditions.
How to Use This Calculator
- Enter the radius (R) of the cylindrical shell in meters.
- Enter the thickness (t) of the cylindrical shell’s wall in meters.
- Enter the internal pressure (P) in Pascals (Pa).
- Click the “Calculate” button.
Formula & Methodology
The formula for calculating hoop stress (σθ) is:
σθ = (PR) / t
where:
- P is the internal pressure,
- R is the radius, and
- t is the thickness of the cylindrical shell.

Expert Tips
- Always consider the material’s yield strength when designing cylindrical shells.
- Don’t forget to account for other stress components, such as longitudinal stress and shear stress.
- Regularly inspect and maintain pressure vessels and piping to ensure their integrity.
Interactive FAQ
What happens if the hoop stress exceeds the yield strength?
The cylindrical shell may deform plastically or even fail, leading to potential leakage or rupture.
