Hoop Stress Thick Walled (Internal Pressure Only) Formula

\(\large{ \sigma_h = \frac{ p_i \; r_i^2 }{ r_e^2 \;-\; r_i^2 }  \; \left( 1 \;-\; \frac{ r_e^2}{r^2} \right) }\)   

Where:

\(\large{ \sigma_h }\)  (Greek symbol sigma) = hoop stress

\(\large{ t }\)  (Greek symbol sigma) = wall thickness

\(\large{ p_i }\) = internal pressure

\(\large{ r }\) = radius to point of intrest

\(\large{ r_e }\) = external radius

\(\large{ r_i }\) = internal radius
