Pressure Loading of Thin-walled Vessels (Sphere) Calculator

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

Formula: $$ \sigma = \frac{P\,r}{2t} $$
with \( \mu_0 = 4\pi \times 10^{-7} \) H/m (used for reference in other calculations).
