Spherical Hoop Stress Thin-wall Section Formula |
||
|
\( \sigma_h \;=\; \dfrac{ p \cdot r }{ 2 \cdot t }\) (Spherical Hoop Stress Thin-wall Section) \( p \;=\; \dfrac{ \sigma_h \cdot 2 \cdot t }{ r }\) \( r \;=\; \dfrac{ \sigma_h \cdot 2 \cdot t }{ p }\) \( t \;=\; \dfrac{ p \cdot r }{ \sigma_h \cdot 2 }\) |

| Symbol | English | Metric |
| \( \sigma_h \) (Greek symbol sigma) = Spherical Hoop Stress | \(lbf\;/\;in^2\) | \(Pa\) |
| \( p \) = Pressure | \(lbf\;/\;in^2\) | \(Pa\) |
| \( r \) = Radius | \(in\) | \(mm\) |
| \( t \) = Wall Thickness | \(in\) | \(mm\) |
