Cylinder stress (hoop stress)


In mechanics, a cylinder stress is a stress distribution with rotational symmetry; that is, which remains unchanged if the stressed object is rotated about some fixed axis. Circumferential stress or hoop stress, a normal stress in the tangential (azimuth) direction, is the force exerted circumferentially (perpendicular both to the axis and to the radius of the object) in both directions on every particle in the cylinder wall.
