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. Cylinder stress patterns include: • circumferential stress, or hoop stress, a normal stress in the tangential (azimuth) direction. • axial stress, a normal stress parallel to the axis of cylindrical symmetry.
