| Abstract: | In this paper,the curved surface membrane element is used to analyze the membrane structures for the first time. All the essential formulas have been derived on the basis of nonlinear finite element theory. New methods and procedures are given for solving the new problems and the old ones arisen in the plane membrane element theory as well. |
