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

\(\large{ \sigma_h = \frac{ - p_e \; r_e^2 }{ r_e^2 \;-\; r_i^2 }  \; \left( 1 \;+\; \frac{ r_i^2}{r^2} \right) }\)
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 \(\large{ in }\) \(\large{ mm }\)
