How does the Pressure Vessel Calculator work?

Thin-walled hoop stress: σ = (P × r) / t Then: Thin-walled longitudinal: σ = (P × r) / (2t) Then: Thick-walled uses complex formulas; pressure determines stress.

Can you give an example of how to use the Pressure Vessel Calculator?

Example: Input Cylinder r=200mm, t=10mm, P=5 MPa gives a result of Hoop stress ≈ 100 MPa (Governs failure mode).

Is the Pressure Vessel Calculator free to use?

Yes — completely free with no registration, download, or subscription required. All calculations happen instantly in your browser.
