| Abstract: | Cubic spline taken as a trial function, under action of axisymmetric line load, nonlinear bending of shallow spherical sandwich shells was calculated. A sandwich plate or shell was assumed to be Reissner＇s model. Results of circular sandwich plates with rigidly clamped edge were compared with those obtained by the perturbation method. All numerical solutions are with high precision. |

| Keywords: | circular sandwich plate shallow spherical sandwich shell large deflection nonlinear stability spline collection method |
