| Abstract: | The structure composed of circular plate, conical shallow shell and annular plate is used widely in the engineering. And one of its important characteristic is elastic jump. Thisarticle analyzed this structure by the nonlinear theory of elastic buckling. Besides, it used integral method and Galerkin method to calculate some bypical examples. The resultS highlight the effects of geometric parameter on the elastic jump characteristic of this strUctUre. The article can provide a basis for the engineering design. |
