The Bending Of Pillars With Four Fix Edges

In this paper, using double Fourier Series, the bending of pillars with four fix edges are analyzed. And in the process, symmetry and the principle of superposition are also be used. Because of using double Fourier Series, the development of equations is very simple, and the answer has the advantages of uniform mathematic examples are worked out by using MATLAB, and some distortion graphics are given under different cases .It is easy to contrast and check.This paper described the use of double Fourier Series calculate the bending of equal thickness isotropic rectangular pillars with four fix edges solve means. This demonstrated the use of double Fourier Series for the use of computer and the results of the feasibility and accuracy. These enrich the theoretical study of the shell, the shell of rectangular pillars, such as engineering design and construction practice is of important guiding significance.
