Pressure Loading of Thin-walled Vessels (Sphere) Calculator
Calculate the hoop stress (pressure loading) using: $$ \sigma = \frac{P\,r}{2t} $$
* Enter the internal pressure \(P\) (Pa), sphere radius \(r\) (mm), and wall thickness \(t\) (mm). The result is shown in pascals (Pa) and megapascals (MPa).
Step 1: Enter Parameters
e.g., 101325 Pa (atmospheric pressure)
e.g., 500 mm (0.5 m)
e.g., 5 mm
