Hoop Stress Formula - Classical Physics


σa =((pi x ri2 - po x ro2) / (ro2 - ri2)) - (ri2 x ro2(po - pi) / (r2 x (r02 - ri2))


σa = Hoop (Circumferential) Stress in Cylindrical Wall or Tube
pi = Internal Pressure in the Tube
po = External Pressure in the Tube
ri = Internal Radius in the Tube
ro = External Radius in the Tube
r = Radius to point in tube
