Application of Finite Element mthod in Plate Bending

The paper based on the analysis of the literature, outlines the application of methods derived from the research of the finite element method. Having compared the research in metal forming with the areas of manufacturing technology can be stated, the metal forming technologies are very suitable for utilising FEM-techniques. The applied approximate formulas do not guarantee accurate results in determination of bending force for long and thick plates, in relation to the size of the bending radius, especially for plates with great wall thickness and the large bending radius. When bending plates is in press tool, it happens very often that punch and the die are of the same size. At one moment the bending force at  L=0 represents infinitesimally great bending force. The paper is concerned with numeric procedure in plate bending. For numeric procedure the finite element method is use. The plate bending analysis is restricted to the data used so far in the manufacture of tanks, i.e. to deformation up to 2%.
