Stretch bending is a stamping process for bending sheet metal, tubing and profiles into workpieces of a certain curvature, shape and size. The stretch bending forming is widely applied to manufacturing of steel plates and ribs of high-pressure containers, boiler drums, boiler tubes, ship bodies, various vessels, instrument and meter components, cabinet panels and the like, and the stress states of all parts in a deformation area of the material are different when the material is subjected to stretch bending. The non-deformed part in the middle of the cross section is called a neutral layer. The metal other than the neutral layer is subjected to tensile stress, and undergoes elongation deformation. The metal within the neutral layer is under compressive stress to produce compressive deformation. Because the stress and strain directions of the metals on the two sides of the neutral layer are opposite, after the load is removed, the elastic deformation recovery directions of the metals on the two sides of the neutral layer are opposite, and the elastic recovery of different degrees is caused.
