Bending in metal forming - springback after bending

The paper is concerned with the numerical method of determination springback after bending. Same is shown in diagrams for some materials. Bending force and calibration force in plate bending are also elaborated. For numeric procedure the finite element method is used. Calibration force is determined when bending force and calibration coefficient are known. Significant factors for determination of bending force are: material of the circular plate, bending radius of circular plate, diameter of the circular plate, thickness of the circular plate and method of loading of the circular plate. The calibration coefficient is determined by experient. The analysis of bending plate is limited to the facts and figures used so far in the fabrication of spherical tanks, i.e. for deformations up to 1%.
