| Abstract: | The semi-analytic method is used to deduce the nonlinear vibration differential equation for a clamped hollow spherical shell under concentrated load in this paper. The nonlinear resonant and non-resonant periodic solutions are obtained by the small parameter methods. The amplitude versus frequency curves for different geometrically parameter are paesented. |
