This tool calculates the hoop stress for cylindrical objects based on the given parameters.
Hoop Stress Calculator
This calculator computes the hoop stress (also known as circumferential stress) in a cylindrical vessel subjected to internal pressure. Hoop stress is crucial for assessing the structural integrity of pressure vessels.
How to Use the Calculator
- Enter the internal pressure (P) in Pascals (Pa).
- Input the inner radius (r) of the cylinder in meters (m).
- Provide the wall thickness (t) of the cylinder in meters (m).
- Click on the “Calculate” button to compute the hoop stress.
- The result will be displayed in Pascals (Pa).
Calculation Details
The hoop stress (σh) is calculated using the formula:
σh = (P * r) / t
Where:
- P is the internal pressure (Pa).
- r is the inner radius (m).
- t is the wall thickness (m).
Limitations
This calculator assumes a thin-walled cylindrical vessel where the wall thickness is much smaller than the inner radius (t << r). It also assumes uniform material properties and loading conditions. The results may not be accurate for thick-walled vessels or materials with varying properties.
