Significant Factors

The paper is concerned with the numerical method of determination bending force and calibration force in plate bending. 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 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 experiment. 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 %.

Linear Smoothing

A number of plate bending elements which include shear suffer from spurious shear effects. So far, however, the techniques that have been used to eliminate these effects involve only the manipulation of the stiffness matrix, and are incapable of accurately predicting the distribution of the shear stress resultants within the element. Herewith, a least squares linear smoothing is applied to the strain matrix of a quadratic, isoparametric symmetrical circular plate element before assembling the stiffness matrix; thereby leading to a better prediction of the stress field within the element.

Thickness Variations

A mathematical model of axisymmetric elastic/plastic perforated circular plate bending and stretching is developed which accounts for through thickness yielding, through thickness variations in perforation geometry, elastic outer edge restraint, and moderately large deflections. Selected numerical solutions of the resulting differential equations are presented graphically and used to illustrate interesting trends.

Axisymmetric Structures

Semi-analytic formulations have previously been used for a number of stressing problems wherein axisymmetric structures have supported non-axisymmetric loads. The approach is here shown to be very useful for circular plates, and to have especial value for design analyses using desk top computers in which the main store is relatively small.
