Hoop Stress Calculator

What is Hoop Stress?

Hoop stress (also known as circumferential stress) is the stress that occurs in the pipe or pressure vessel walls. It is an important parameter in mechanical engineering that helps determine the structural integrity of pressure vessels under internal pressure.

How to Use the Calculator

1. Enter the radius of the pressure vessel or pipe in meters.
2. Enter the thickness of the wall in meters.
3. Enter the internal pressure in Pascals.
4. Click the "Calculate" button to compute the hoop stress.
5. The result will be displayed in Pascals.

Working Principle

Hoop stress is calculated using the formula:

σ = P × r / t

Where:

• σ = Hoop Stress (Pascals)
• P = Internal Pressure (Pascals)
• r = Radius (meters)
• t = Thickness (meters)

Applications

Hoop stress calculations are essential in various engineering applications such as:

• Designing pressure vessels for oil and gas industries
• Engineering pipelines for water or chemicals
• Designing storage tanks for industrial use
• Ensuring the safety of mechanical components under pressure
