【Abstract】 The finite element method is used to analyze the static and dynamic behaviors of a non cylindrical shell based on the plate and shell theory. The stress distribution and the variation of load bearing capacity in the non cylindrical shell with various forms and parameters of the structure are compared. An analytical expression for the cylindrical part is given. To ease the application in engineering designs, some simple computing methods are discussed, and the calculation result of 3 different methods are compared. Model tests verify the reliability of the theoretical analysis.更多还原
