Spherical Hoop Stress Thick-walled Section (Internal Pressure Only) Formula

\( \sigma_h \;=\;  [\;  p_i \; r_i^2 \;/\; r_e^2 - r_i^2 \;]  \;  [\; 1 - (r_e^2 \;/\; r^2) \;] \)
 Symbol English Metric
\(\large{ \sigma_h }\)  (Greek symbol sigma) = Spherical Hoop Stress \(lbf\;/\;in^2\) \(Pa\)
\(\large{ p_i }\) = Internal Pressure \(lbf\;/\;in^2\) \(Pa\)
\(\large{ r_i }\) = Internal Radius \(in\) \(mm\)
\(\large{ r_e }\) = External Radius \(in\) \(mm\)
\(\large{ r }\) = Radius to Point of Intrest \(in\) \(mm\)
