Cylindrical stress path
WebIn 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. axial stress, a normal stress parallel to the axis of cylindrical symmetry. WebIn any pressure vessel subjected to internal or external pressure, stresses are set up in the shell wall. The state of stress is triaxial and the three principal stresses are: x¼ longitudinal/meridional stress ¼ circumferential/latitudinal stress r¼ radial stress In addition, there may be bending and shear stresses.
