Longitudinal Hoop Stress Thick-walled Section (External Pressure Only) Formula

\( \sigma_h \;=\;   \dfrac{  - p_e \cdot r_e^2 }{ r_e^2 - r_i^2 } \) 
 Symbol English Metric
\( \sigma_h \)  (Greek symbol sigma) = Hoop Stress \(lbf\;/\;in^2\) \(Pa\)
\( p_e \) = External Pressure \(lbf\;/\;in^2\) \(Pa\)
\( r_e \) = External Radius \( in \) \( mm \)
\( r_i \) = Internal Radius \( in \) \( mm \)
