Application of FEM in plate bending

The paper is concerned with the numeric procedure in axial-symmetrical plate bending. For numeric procedure the finite element method is used. Calibration force is determined when bending force and calibration coefficient are known. The calibration coefficient is determined by experiments. The axial symmetrical plate bending analysis is restricted to the data used so far in the manufacturing of spherical tanks i.e. to deformation up to 2%. To obtain equations for the calculation of force for axial symmetrical plate bending and displacement during loading procedure andd after its removal, data obtained by finite element method were used. The method of least square was used to interpolate the results. Mathematical procedures were used to obtain equations for the calculation of force and displacements, the equations being of use for solving practical problems.
