WebBending is a metal forming process in which a force is applied to a piece of sheet metal, causing it to bend at an angle and form the desired shape. A bending operation causes deformation along one axis, but a sequence … 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.
