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

\(\large{ \sigma_h = \frac{ p_i \; r_i^2 }{ r_e^2 \;-\; r_i^2 }  \; \left( 1 \;-\; \frac{ r_e^2}{r^2} \right) }\)
 Symbol English Metric
\(\large{ \sigma_h }\)  (Greek symbol sigma) = spherical hoop stress \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ p_e }\) = external pressure \(\large{\frac{lbf}{in^2}}\) \(\large{Pa}\)
\(\large{ r }\) = radius to point of intrest \(\large{ in }\) \(\large{ mm }\)
\(\large{ r_e }\) = external radius \(\large{ in }\) \(\large{ mm }\)
\(\large{ r_i }\) = internal radius \(\large{ in }\) \(\large{ mm }\)
