For bending problems of the general axisymmetric shell, the finite difference method has been widely used as well as the finite element method, and B.Budiansky and P.P.Radkowski have proposed a finite difference method based on Sanders' shell theory. In this paper, two numerical methods for statical bending and free vibration problems of the general axisymmetric shell are pressented. One of them is based on Flugge's shell theory, which is well used in our country, and the other is based on Mizoguchi's shell theory, the utility of which has been probed especially for various problems of cylindrical shells. The above-mentioned two methods are described by the equations of the same form as those by Budiansky and Radkowski, only the coefficients of which are different. These three methods are applied to some statical bending and free vibration problems at the same time, and it turns out that the results by these methods almost coincide with each other.
