Hoop Stress Thick walled (External Pressure Only) Formula

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

Where:

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

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

\(\large{ p_e }\) = external pressure

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

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

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