A semi-analytical approach to investigate the nonlinear vibration axisymmetric analysis of FG-GPLRC shallow spherical shells under external pressure resting on visco-elastic foundation is presented. The governing equations are derived by using the first-order shear deformation theory (FSDT) taking into account von Karman geometrical nonlinearity and visco-elastic foundation. The motion equations are determined by Galerkin method and the obtained equation is numerically solved by using Runge–Kutta method. Results of nonlinear dynamic responses show the effects of foundation, material, geometric parameters on the nonlinear vibration of shells.
