Circumferential shear stress
WebOct 12, 2011 · The three principal Stresses in the Shell are the Circumferential or Hoop Stress, the Longitudinal Stress, and the Radial Stress. If the Cylinder walls are thin and the ratio of the thickness to the Internal diameter is less than about , then it can be assumed that the hoop and longitudinal stresses are constant across the thickness.
