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
\( \sigma_h \) (Greek symbol sigma) = Hoop Stress	\(lbf\;/\;in^2\)	\(Pa\)
\( p_e \) = External Pressure	\(lbf\;/\;in^2\)	\(Pa\)
\( r \) = Radius to Point of Intrest	\( in \)	\( m m\)
\( r_e \) = External Radius	\( in \)	\( mm \)
\( r_i \) = Internal Radius	\( in \)	\( mm \)
