Based on the Reissner assumption and the variational principle, the large deflection equation of the flattened spheroidal shell under uniform pressure is given. The analytical solution to the nonlinear stability problem of the spherically-flattened spherical shell is obtained by the modified iterative method. The critical buckling loads The effects of geometric parameters and physical parameters on critical buckling loads are discussed
