【Abstract】 From Von Karman’s large deflection equation of the plate and by assuming that a plate has initial deflection in the form of a spherical cap,the equilibrium equation of a spherical cap subjected to hydrostatic pressure is obtained,simplified and solved in the same way as an equilibrium equation of a beam on an elastic foundation subjected to axial and lateral loads. The method presented for calculating deformation and stress of a general spherical cap and spherical-zone shell in shipbuilding and maritime engineering is obtained and applied to the design for hemispherical shell with large hole.It is shown by analyzing the results and test data ,that the method has the advantage of simplicity and accuracy of calculation.更多还原
