| Abstract: | To calculate the elastic stability of overall stiffened structure of missile shell under axial compression, the paper presentes a practical finite element model, so that the very nonlinear problems are linearized and the stability calculation of the overall structure is greatly simplified. Based on the computing model of this paper, the numerical results of finite element method are in better agreement with its experiment results. |
