Analysis of circular plates is important in the design of a cover of pressure vessel or a cover of piping systems. Recently, finite element method has widely been used in design of these products. However, the importance of the analysis of circular plates based on the strength of materials is still high. One of the problems of the analysis is the variation of the thickness of the plate and a nonuniform pressure on the plate cannot be fully taken into consideration and a simplification of these effects can lead erroneous results. In this paper, a plate is divided into several parts and the plate is analyzed considering the continuities of these parts. The advantage is the variation of the thickness of plate can be considered. The validity of the method is confirmed by comparing the calculated results with those obtained by FEA.
